X-21 Flat Base (Enamel) 80021

I brushed this over a glossy finish expecting a subtle dull-down, and it killed the shine exactly how I wanted. A little goes a long way, so the small jar will last me through several kits.

Mixed a few drops into gloss enamel and it killed the shine exactly how I wanted, no chalky look at all. The bottle is small but a tiny amount goes a long way, so it'll last through plenty of projects.

Didn't expect one little bottle to change my whole finish game, but a couple drops of this in my clear coat killed the shine perfectly. Dries flat and even, no chalky white haze like some matte additives leave. My tank models finally look right.
