When I bought my car it had lots of rust on the door trim and I wanted to fix that. During the summer me and my dad fixed that by sanding down and repainting the entire door trim including two rear trunk windows with a couple coats of primer and rustoleum semi gloss black. It's almost spring now and it has held up well. I'll post pictures later because I'm busy today, but my question is... How can I keep the paint looking new. We did not put any clear coat because it would make it look real shiny which I do not want but so far it has held up real well. Any tips I can use to maintain my paint job?
