Hey guys. I've got a raw aluminum gas tank I'm trying to polish up, right now I'm just on 220 sand paper and I'll work my way up to 1800-2000 but after that I'm wondering what people use for rotary polisher? I was thinking about getting a Makita but there just a little expense for a tool I won't use to much. But has anyone used one before and have any thoughts on it or one like it. Also are people cleaner coating the button of there raw tanks?
