Yeah, there's a lot of snake oil in the "high end detailing" market I suspect. But of course when some rich ******* overpays a "celebrity detailer" to take care of his car, he wants them to use ridiculously overpriced products to do it also, I guess.
I think it's kind of like the audiophile cable thing, people think a $2000 digital cable is better than a $20 digital cable. Even though they both pass ones and zeroes, and either work or don't work...
Yeah and not to mention any nooks and crannies on the bike, and even in between the nuts and bolts if you are unlucky which can promote corrosion. If you very carefully spray the billet parts of the wheels and stay away from any seams of any kind, maybe, but going with a more gentle flow is fine for lifting the worst particles off before you start in with a foam gun or just a wash mitt and some car shampoo.
I just polished my rear fender last night with some Meguiar's M105 ultra-cut compound and the dual action to get the marks out where the stock 2-up seat had rubbed circles into it (putting a Mustang solo one on)... very satisfying to see it turn into a clear mirrored surface again, still going over it with some 205 tonight and then some wax.
