I used Duracoat with a cheapo air brush on my glock slide. I got excited and didn't quite follow all the surface prep guidelines and it looked like crap after about a month. Paint peeling and scraping off. Blasted the duracoat off and a little more, recoated it, and it has held up fine since then. Looks better too. My first time around I topcoated with Matte clear. The matte finish, like flat wall paint seemed to get dirty easier. I went with semi gloss clear this time and and carbon or residue on it just wipes off with a rag.
