Hobby Supplies – Model Paints, Primers, Hobby Tools, Weathering Effects, and Finishing Materials for Model Kits and Miniatures
A model kit out of the box is a collection of plastic runners. The tools, paints, and finishing materials are what transform that plastic into a display piece worth putting on a shelf. Even builders who prefer the "straight build" approach — snap-fit assembly with no paint — benefit from a good pair of nippers, a hobby knife, and a set of panel-lining markers, because the cleanliness of the build depends on how well parts are separated from the runner and how precisely gate marks are trimmed. For builders who paint, weather, and detail their kits, the supply list grows into its own ecosystem of primers, paints, thinners, brushes, airbrushes, masking materials, decal solutions, and topcoats. Understanding what each product does and when to use it is the difference between a finished kit that looks amateur and one that looks professional.
Model Paints – Acrylic, Lacquer, and Enamel
Model paints are formulated specifically for scale modeling — their pigments are ground finer than craft paints, their viscosity is tuned for thin-coat application over small surface areas, and their chemistry is designed to bond to the plastics, resins, and metals used in model kit construction. Choosing the right paint type is one of the first decisions a builder makes, and it affects every step of the painting process from thinning to cleanup.
Acrylic paints are water-based (or alcohol-based, depending on the brand), low-odor, and clean up with water or isopropyl alcohol while still wet. They dry fast, build up in thin coats without obscuring surface detail, and are the safest option for indoor use without dedicated ventilation. Acrylics are the standard recommendation for beginners because they are forgiving — mistakes can be corrected quickly, thinning ratios are flexible, and the health risks are minimal compared to solvent-based alternatives. The tradeoff is that acrylics are slightly less durable than lacquers and enamels once cured, and their fast drying time can cause tip-dry when airbrushing (paint drying on the needle tip and disrupting the spray pattern), which requires the use of flow improvers or retarders to manage.
Lacquer paints are solvent-based and produce the smoothest, most durable finish of any model paint type. They dry extremely fast, self-level well when airbrushed (producing a glass-smooth surface), and bond aggressively to plastic — lacquer solvents partially melt the surface of the plastic, creating a chemical bond that is stronger than the mechanical adhesion acrylics rely on. Lacquer is the preferred paint type for base coats, automotive finishes, candy coats, and any application where a flawless, handling-resistant surface is the goal. The tradeoff is that lacquer solvents produce strong fumes that require proper ventilation (a spray booth with exhaust) and respiratory protection (a half-face respirator with organic vapor cartridges) during application. Lacquers are not beginner-friendly without the appropriate safety setup.
Enamel paints are oil-based and dry through a slow curing process rather than solvent evaporation. Their extended working time — significantly longer than acrylics or lacquers before the paint sets — makes them excellent for brush painting because the paint self-levels and hides brush strokes as it cures. Enamels are also the preferred paint type for washes (thinned paint flowed into panel lines and recessed detail to add shadow and depth) and filters (very thin paint applied over a base coat to shift its color tone subtly) because the slow drying allows controlled manipulation of the paint on the surface before it sets. Enamel thinners and cleanup require petroleum-based solvents (mineral spirits, white spirit, or brand-specific enamel thinners), which produce fumes that also require ventilation.
Oil paints are used almost exclusively for weathering in scale modeling. Their extremely long drying time (hours to days) allows advanced techniques like dot filtering, streaking, fading, and blending directly on the model surface. Oil paints are applied over a sealed base coat (typically a gloss or satin clear coat that protects the underlying paint from the oil solvents) and can be manipulated, blended, and removed for extended periods before they cure.
Preparation and Finishing
Preparation and finishing products handle everything that happens before and after paint.
Primer is a preparatory coating applied before paint to create a uniform surface that paint adheres to evenly. Bare plastic varies in color, texture, and surface energy depending on the material and manufacturer — primer normalizes all of this into a consistent, paint-ready surface. It also reveals surface imperfections (scratches, mold lines, sink marks, seam lines) that are invisible on raw plastic but become glaringly obvious once color paint is applied. Catching these at the primer stage saves the frustration of discovering them after detailed painting is complete. Primer is available in spray cans (fast, even coverage over large surfaces) and bottled liquid (applied by airbrush for finer control and thinner coats over delicate detail). Common primer colors are grey (the most versatile, works under any paint color), white (for bright colors that need a light undercoat to appear vibrant), and black (for dark schemes and the popular black-basing or pre-shading technique where the black primer shows through lighter top coats at panel line edges to create natural shadow).
Surfacer is a thicker primer variant that fills minor imperfections — shallow scratches, faint mold lines, and pinholes in putty work — that standard primer cannot cover. Surfacer is available in grits (500, 1000, 1500) that indicate the smoothness of the cured surface, with higher grit numbers producing a finer, smoother finish. Using 1500-grit surfacer before painting produces a surface smooth enough for high-gloss finishes.
Putty is used to fill gaps between mated parts, repair surface damage, and sculpt new detail. Basic model putty is a two-part or single-part compound that hardens after application and is then sanded smooth. Instant-setting putty alternatives use cyanoacrylate (super glue) accelerated with a spray activator for fast gap-filling that can be sanded within minutes. Epoxy putty (two-part kneadable compounds) is used for sculpting modifications and building up structural shapes.
Sanding progresses through grits — lower numbers (200-400) remove material aggressively for reshaping and removing heavy imperfections, middle grits (600-800) smooth surfaces for painting, and higher grits (1000-2000 and above) polish surfaces to prepare for gloss finishes. Sanding sticks, sponge-backed sanding pads, and flexible sanding cloths provide different shapes and compliance for reaching flat surfaces, curved areas, and recessed detail without distorting part geometry.
Topcoat (clear coat) is the final protective layer applied over a completed paint job. Matte topcoat eliminates gloss and gives a flat, realistic military or mechanical appearance. Satin topcoat provides a subtle sheen that splits the difference between matte and gloss — the most natural-looking finish for most subjects. Gloss topcoat produces a high-shine surface that suits automotive models, certain mecha designs, and any surface that needs to reflect light. Beyond aesthetics, topcoat protects the underlying paint, decals, and weathering from handling damage, UV fading, and environmental exposure.
Effects and Textures
Effects and textures take a cleanly painted model and make it look like it exists in a real environment — used, weathered, battle-damaged, dusty, rusted, or mud-caked depending on the subject and the story the builder wants to tell.
Panel line accent (often called panel liner or panel wash) is a thin, highly fluid paint that flows into the recessed lines on a model's surface through capillary action, darkening the panel lines and enhancing the three-dimensional detail that is molded into the kit but nearly invisible without paint. Enamel-based panel liners are the most popular because their slow drying allows cleanup of excess paint from the flat surfaces with a cotton swab dampened in thinner, leaving clean lines without affecting the base coat underneath.
Weathering pigments (dry powdered pigments in earth, rust, soot, and dust tones) are brushed, stippled, or fixed onto surfaces to simulate accumulated grime, exhaust residue, and environmental exposure. They adhere to matte and satin surfaces through mechanical adhesion and can be sealed with a light mist of fixative or matte topcoat for permanence. Weathering pencils and weathering markers provide more controlled application for localized effects like chipping, scratches, and rain streaks.
Metallic pigments and metallic paints reproduce the appearance of bare metal, chrome, burnished steel, copper, brass, and gold on model surfaces. The finest metallic pigments (like those used in high-end chrome lacquers) require a perfectly smooth, gloss-black base coat to achieve a mirror-reflective finish that is virtually indistinguishable from actual polished metal at scale viewing distances.
Decal solutions include setting solution (which softens decals so they conform to curved and textured surfaces without silvering — the visible air trapped under a rigid decal edge) and solvent solution (which further melts the decal film into the surface for a "painted on" appearance). Proper decal application over a gloss surface with setting solution eliminates the decal-sticker look that undermines otherwise well-painted builds.
Hobby Tools and Equipment
Hobby tools are the physical hardware that a builder uses at every stage of construction and finishing.
Nippers (side cutters or sprue cutters) are the most-used tool in model building. They cut parts from the plastic runner (sprue) at the gate — the thin connection point between the runner and the part. Single-flush nippers cut flush on one side, leaving a smaller gate mark that requires less cleanup. Ultra-thin, precision nippers (like those designed specifically for Gunpla) produce an even cleaner cut on softer plastics but are not intended for thick gates, wire, or hard materials and will break if misused. A two-cut technique — first cut away from the part to separate it from the runner, then a second precision cut close to the part surface — produces the cleanest results and protects expensive nipper blades from stress damage.
Hobby knives handle trimming, scraping, and precision cutting. A #11 blade (pointed, straight-edge) is the standard for trimming gate nubs, scribing panel lines, and fine cutting. Curved blades handle rounded surfaces. Chisel blades scrape flat surfaces clean. Blades dull quickly on plastic and should be replaced frequently — a dull blade requires more force, which increases the risk of slipping and damaging the part or cutting your hand.
Files and sanding sticks smooth surfaces after cutting and before painting. Metal files remove material quickly for reshaping. Glass nail files and fine-grit sanding sticks smooth gate marks and seam lines without leaving deep scratches. Progressive sanding — starting at a lower grit and working upward through finer grits — produces the smoothest possible surface with minimal work at each stage.
Tweezers handle small parts, decals, and photo-etch components that are too small or too delicate to grip with fingers. Pointed-tip tweezers provide precision for placing micro-decals and tiny parts. Flat-tip tweezers grip wider components without crushing them. Reverse-action tweezers (which grip when released rather than when squeezed) are useful for holding parts during gluing and painting.
Cutting mats protect the work surface from knife cuts, glue drips, and paint spills. Self-healing mats in A3 or A4 size are the standard — the mat surface closes behind knife cuts rather than developing permanent grooves, which extends the life of the mat and keeps the surface flat for accurate cutting.
Airbrushes are the tool that separates casual builders from dedicated modelers. A gravity-feed, dual-action airbrush (where pushing the trigger controls air and pulling it back controls paint flow) provides the finest control over paint delivery, allowing everything from broad base coats to tight freehand camouflage lines. Airbrushes require a compressor with a regulator and moisture trap, and the combined setup runs through a spray booth with an exhaust fan when using lacquer or enamel paints. For builders not ready to invest in an airbrush system, rattle-can spray primers and topcoats combined with hand-brushed detail painting produce respectable results without the additional equipment.
Building a Supply Kit by Skill Level
A beginner kit needs nippers, a hobby knife with #11 blades, a sanding stick or set of fine files, a cutting mat, a panel-lining marker (fine-tip grey or brown), and a can of matte topcoat. This handles clean snap-fit builds with basic panel lining and a protective finish. A mid-level kit adds spray primer, a set of acrylic paints, fine-tip brushes, masking tape, decal setting solution, and matte and gloss topcoats — enough to build, prime, paint, decal, and seal a fully detailed kit. An advanced kit adds an airbrush, compressor, spray booth, lacquer paints, weathering pigments, enamel washes, oil paints for blending, and the full range of sanding grits for contest-level surface preparation. Each level of tooling opens new techniques without making the previous level's tools obsolete — the nippers, knife, and cutting mat from the beginner kit are still used every single build at the advanced level.
