I'm currently doing a test on 2 sets of wheels, one set wearing CG Wheel Guard, the other wearing Raceglaze nano wheel sealant.
I feel it's a pretty fair test, it seems to me that the two products are priced pretty similarly.
From experience, Wheel Guard certainly adds it's bit of beading and protection (brake dust is easier to remove) but I can't help but feel its longevity is limited to around 2-3 months. I'm not disappointed with Wheel Guard, but now I've got the Raceglaze as a competitor, so we'll see
