So the idiots I took my S&S coupled frame to decided to powdercoat the couplers even though I specifically told them not to. I am now about to begin sanding the powdercoat off. What process would be recommended for this? I believe that the couplers are stainless steel. I know some will say: why don't they fix it? Well, it is a long story but suffice it to say that I'd rather just take care of it myself.
So far I have started with 80 grit paper, and am thinking I will use that until I have mostly metal exposed, then I will step down to 220 and follow it with 400 or something like that if it looks like it is needed. After that, I have some rubbing compound and other mystical wet sanding liquids from my automotive days laying around that I figure I could finish the couplers and lugs off with.
My main concern is that starting with 80 grit could somehow damage the coupler or be too rough on the finish. Opinions?
