Pretty darn well. I've painted just about every gun I have with it in some form or another.
When I build AR's I'll duracoat Ultra flat tactical black to get the upper, lower, and barrel to all match. Lately ultra flat tactical flat dark earth... It's my new obsession.
I've scraped them on my steel seat mounts and other things putting them in the back of my jeep and it didn't scratch chip or flake... just got a shiny mark there when you look at it at a certain angle in a certain lighting.
Usually do all my camo with it.
If you prep it right and paint it right and let it cure right it's on for life. ...just about.
It's even a b*tch to strip with chemical stripper.
