Ay up chap
Yeah I use them a fair bit on my cossie and GSXR parts...brings them up mirror finish, as long as you take your time....it aint a quick process tho and ive found that the best why is to get it as good as you can with 1200 grit 1st and then go onto the mops. Wear eye protection and a mask tho or else you'll have panda eyes and black snot for days lol
