whats up,
ive been reading this great forum for a yr or 2 and this is my first post!
I have found that when polishing aluminum ZOOP metal polish is about the best you'll find,it works in 2 or 3 stages..it's been awhile since i've used it,But I did use it for an car amp heatsink...came out looking like a mirror! and stayed that way for 2 yr's! hope this helps..
