Has anyone done this and then wet sanded the touch up paint and then buffed it? How is the result?

 

Yep, I just did that to my 2000 Camaro. But make sure you go and get the "original" paint form the dealer. My Actic white touch up paint only cost me 3 bucks. for small chips I'd get the brush on type and take your time with it, dont put a glob of it on cause it will look cheap. But wash your car first then brush it on very lightly, then after it dries put a nice coat of wax on. Mine came out great and you cant tell unless you get all the way up on the car ( I mean real close). Main thing "take your time"
