Krylon Fusion FTW x2! you can get it at wally-world for like 3-4 bucks I believe. AFAIK
, you only use it on plastic. It comes with directions. The biggest thing is just making sure the base coat has something to stick to. Cleaning the surface is number one, scuffing it up number two. realistically anything from 220-400 is plenty just go over all areas you want to paint just so they arn't smooth/slick. You can go with the camo fusion flat black as a base coat with 2-3 coats and then whatever color over that. I've never used clear over it so I can't say as to use it or not. I know one thing to make it look good, don't spray TOO much on at one time and make it run. take your time, stay about 12-15 inches away and spray quick light shots sort of overlapping the previous one. It's okay if you start out and you can still see underneath your first coat. it's better to be a little light and let it dry and know it's going to look good than to focus on one area and make it look dumpy. DON"T use fusion and then switch to something else. use FUSION all the way if you start with fusion. it's great stuff and cheap.
