I'm not really an idiot, but I just bought a dremel tool and polishing accessories. I am new to using a tool like this but I'm a smart guy. I plan on going very slowly until I get the hang of it because I do NOT want to ruin any of my firearms. Any advise would be greatly appreciated. Also, is there anything that I could practice on that would be similar to a firearm? I plan on polishing a feed ramp or two. Also, on my new EG mak the hammer and safety is a weird color. What would happen if I tried to polish the hammer and safety, and maybe the slide release????
