Holographic Rainbow Base Coat

How to Use This Product

Holographic finishes use flat, diffraction-grating flake or fine glitter that splits light into a visible rainbow spectrum as your viewing angle changes, rather than reflecting a single colour the way a standard metallic does. A gloss black base coat gives the strongest contrast for that rainbow effect to read clearly against; on lighter bases the diffraction pattern is much harder to see. Controlled, even coats matter more than usual here too, since holographic flake can clump or lie unevenly if applied too heavily in a single pass.

Using the 400ml Aerosol

Ready to spray straight from the can — no mixing required.

1. Shake the can vigorously for at least 2 minutes before use — the agitator ball inside needs to fully mix the pigment. This is the single most common cause of uneven effects when skipped.
2. Hold the can 20–30cm (8–12 inches) from the surface and test your spray pattern on cardboard first.
3. Apply 2–4 thin, even coats rather than one heavy coat, flashing off each coat for around 5 minutes before the next.
4. After use, invert the can and spray for 2 seconds to clear the nozzle and prevent blockages.

Using the Spray Gun Mix

This concentrate needs thinning before it will spray correctly through a gun — it is not ready to use straight from the tin.

1. Shake thoroughly, then mix at a 1:1 ratio with reducer/thinner (equal parts paint and thinner) as a starting point — add a little more thinner if the mix still feels thick.
2. Use an HVLP spray gun fitted with a 1.3–1.5mm tip, at roughly 20–30 PSI.
3. Always spray a test card first and adjust the fan width and fluid control before touching your actual surface.
4. Hold the gun 15–20cm (6–8 inches) from the surface, moving in smooth, overlapping passes with around 50% overlap.
