Lol, I've seen newbs at the dealer really hose it, puddles & drippin' everywhere,....lolol!! It DOES have a preservative effect on stuff like bare aluminum, plastics, etc. that lasts a little while,.....so it's not total BS. It does present much better & helps it stay that way for a while, as long as it's done right anyway, My 'rolla could use a redo at this point...all over!
