I have a set of SS headers i bought off ebay so far i have tried a bit for my die grinder that is for paint removal, definitely left scratches but I can clean that up, also tried maroon scotchbrite pad which works pretty well, and some "nevr dull" I think the scotchbrite and then the nevr dull is the best setup so far

Im not looking for perfection its going a bike i want to get rid of but at least want to make the header look a little better worst case scencario it gets wrapped so theres no pressure at all lol
