Vallejo Premium Color RC White Primer 60ml for Airbrushing, Acrylic-Polyurethane Paint for Models

This Vallejo Premium Color RC White Primer is a water-based acrylic-polyurethane hybrid primer designed for model builders, RC enthusiasts, and customizers. It comes in a 60 ml (2.02 fl oz) bottle with a matte finish. The primer bonds well to surfaces like fiberglass, polyethylene, polycarbonate, metal, and lexan, and it stays color-stable when exposed to RC fuel with up to 35% nitro content after proper curing. Suitable as a base coat to prepare surfaces for painting, it is non-toxic and easy to thin, mix, and clean up.

Why Use a Primer for RC and Model Painting?

A primer acts as the foundation for your paint job. It ensures better adhesion of the topcoat and provides a uniform surface, especially important on slick materials like lexan or polycarbonate used in RC car bodies. This Vallejo primer is formulated to be flexible and durable, resisting impacts, chipping, and cracking. It also helps protect against weather and fuel exposure.

Surface Preparation and Adhesion

For best results, start with a clean, degreased surface. Wash the model to remove any release agents that might interfere with adhesion. Vallejo recommends applying this primer directly onto clean plastic, metal, or wood. On some surfaces, a basecoat of Polyurethane Primer (62.601) may improve adhesion, though this product already bonds strongly to a wide range of materials without extra steps.

Compatibility and Fuel Resistance

After proper curing, this primer resists fuel mixtures containing up to 35% nitro, making it a reliable choice for nitro-powered RC vehicles. It also withstands prolonged outdoor exposure without fading or cracking.

How to Apply This Primer

Vallejo Premium Colors are self-leveling and flow smoothly. For airbrushing with a 0.3 mm nozzle, use the paint directly from the bottle. For smaller nozzles (0.2 mm or less), thin with Vallejo Reducer (62.068). Recommended compressor pressure is 30-60 psi (2–4 bar). You can also apply it with a brush. For maximum protection, topcoat with a catalyzed urethane clear varnish.

Yes. The manufacturer states it bonds well to polycarbonate and lexan surfaces, which are common in RC car bodies.

Do I need to thin it for airbrushing?

With a 0.3 mm nozzle, you can use it straight from the bottle. For finer nozzles, thinning with the appropriate reducer is recommended.

Is the primer fuel resistant?

Yes. After proper curing, it maintains color stability when exposed to RC fuel with up to 35% nitro content.

Is it safe to use indoors?

This primer is water-based and non-toxic, making it suitable for indoor use with good ventilation.
