Quick answer
Use the RCM032 Real Colors Gun Metal marker straight from the bottle with a fine brush or directly on small parts for a fast, durable metallic finish. Shake well, apply thin layers, and let each dry before adding weathering.
Why Gun Metal markers work for metallic finishes
The RCM032 Real Colors Gun Metal marker uses a special acrylic formulation that is fast-drying and waterproof, making it ideal for layering without smearing or removing underlying paint. Its high coverage means one or two coats are enough on most plastic, resin, or metal surfaces.
Unlike standard acrylics, this marker does not blur when applied over other paints, and it stays put under weathering products. This lets you build up a realistic gun metal sheen without worrying about reactivation.
Trade-offs to consider
Because the paint is water-resistant and heat-resistant once dry, you must clean brushes and tools with solvent or isopropyl alcohol immediately after use. The marker tip is best for small details; for larger flat panels, you may prefer to decant the paint and use an airbrush for a more even coat.
The Gun Metal color is a mid-tone metallic gray, not a dark black. If you need a darker shade, apply over a black primer or mix with another Real Colors marker.
Step-by-step: Applying Gun Metal finish with RCM032
- Prepare the surface: Clean the part with mild soap or isopropyl alcohol to remove mold release. Lightly sand with 1000-grit if the plastic is glossy. A matte surface helps the marker adhere evenly. Skip sanding only if the part is already matte; a glossy surface may cause the paint to bead.
- Shake and activate the marker: Shake the RCM032 marker vigorously for 30 seconds. Press the tip down on a scrap surface until paint flows. Test on a paper towel to ensure steady flow before touching your model. If the paint is too thick, dip the tip in water or acrylic thinner briefly; do not thin inside the marker.
- Apply thin layers: Draw the marker gently across the part in one direction. Do not press hard—let the paint wick out. Apply a second coat only after the first is dry (about 5-10 minutes). Two thin coats give a uniform metallic sheen. One thick coat will pool and leave brush marks; thin layers are key to a smooth finish.
- Weather or seal (optional): Once the paint is fully dry (30 minutes), you can apply panel liner, wash, or drybrush. The marker’s waterproof formula prevents lifting. For a protective topcoat, use a clear acrylic spray or varnish. Test weathering on a scrap first—some enamels may stain the acrylic if left too long.
