ok bro first off welcome to the forum, second relax and read the following thread first. it has a lot of good info. it is polishing a motorcycle frame but the methods are the same for most all metals. that said i could walk you through the entire process but would probably bore you with it and that thread at least has pictures even though some of the humor is off color. after looking through the first part that is written and shown if you still have questions post them and i will be more than happy to help you get the finish you want.
