Thanks. I might try it on my son's charger... it's black and needs some correction for swirls etc. so, I'm thinking of getting the 15MM SK, some correcting polish, and then maybe finish with the ceramic spray? is this a good combo? As for my blue baby... it's loaded with wax so rather than start again, I might just leave it be as the paint underneath is perfect and it's got at least 3 coats of wax not to mention some h20 G&G, hate to strip all that off LOL... but the black one I think I'm going to take the plunge and try it myself.. I did just see in IG that a new SK 15MM is coming soon? should I wait for this or no real difference?
