Why does no one recommend rust-o-leum paint for touch-ups to blemishes on an AR?  Now I wouldn't recommend painting the whole thing, but I think light touch-ups would be perfect for rustoleum to handle.  It handles high heat well and works great on the bbq grill.  It's a bit thick if you overdo it, but lightly apply it to small spots doesn't seem too bad.

Now mind you, I don't really care about stuff that happens while using the gun, but I can't stand it when I do something stupid and ruin a gun's good looks.  Scars from use tell a story.  Scars from stupidity are a permanent reminder of what a dumb@$$ you are.

I’ve used Krylon on the rail of my upper receiver after I did some machining work to bring them into spec. Also on the backside of my FSB to cut down on glare.

Is Krylon the same as rustoleum?

I’ve had equal results with both brands. Only spray paint I stay away from is the cheap Wally World .97 cent cans!

I've used some for small touchup areas.  For instance a little blemish on my lower I made when putting in the bolt catch pin.  Used a toothpick to just put a dab on the spot.... Looks like it never happened.

I have read several threads on snipershide where guys use do Krylon cammo jobs on their rifles.  IN fact Krylon now makes 9 different colors of "cammo" paint

Krylon on my Mutt gun, has held up for about 1K rounds and lots of dropping, transitions, rattling arounf in the back of the truck, etc, etc...

Only wear is around the flip up caps on optic and brass defelctor...there're a lot of Krylon nay sayers and I recognize the benefits of Durakote and Norell's, but I'm a fan...

Duplicolor high temp engine enamel. The 1200 degree version that has the ceramic.  Bake it on for a couple hours, and it gets very tough.  It also won't burn and smoke if you paint your barrel and gas tube.

Word, if properly prepped it will stay on NO MATTER WHAT (aside from abrasions.)  I have painted exhaust components with it and they hold up during racing conditions at high EGT.  Stays on with washings and everything except scraping it on the ground when bottoming out.
