A little while back my Glock 32 took a nasty spill and the slide got scratched up in a few places. Naturally, It's going to get another coat of paint. My question is, how can I smooth out the scratches in the metal prior to painting the slide? They aren't too deep at all. Most of it is actually just the finish just wearing off but in a few places it has slightly dug into metal. I've got some pics here to give you a better idea of what I'm talking about. Thanks in advance for your help!
