Since I couldn't buy new repops for my 300, I had to fix what I had. I bought 2 sets to get 1 set that I could fix.
I bumped out the dings, filed and sanded them down, and then I buffed them with a buffing wheel and assorted compounds. Eastwood has some polishing kits and you can buy a buffer at Harbor Fright. They came out decent, much better than how they first looked. Of course... Now they are starting to sell repops for the C bodies.
Or.... You can just buy a set of repops....
