Ok so I got all my pipes smooth as glass. Now my prob is, no matter what, I cant get them to shine? Any tips? What I have done so far is taken a bench grinder and used the fine wire disk to get all the paint of(still left it without scorns). Then I wet sanded it with 600 grit paper. Then I wiped the pipes down and attached the buffing wheel to my bench grinder. No matter what I do they just come out looking dirtier then when I started!!! what do I do? Also I got my plenum polished from Antonio at topspeed(was soo nice when I got it) Then it got dirty from sitting around and getting moved around. How to I get it to shine again?
