Well for all you that have asked. i have used a wire wheel and a buffing wheel. if you try it dont! push on to hard with the wire wheel or it will scuff up your pistons and make it look a mess. also you can not get into all the little gaps on your leaver and your pistons. there will be some little tiny bits that you will have to give up on. but apart from that the results are wicked. keep them shiny with a bit of polish
