[Shoyu Burner]

I used 303 on my S2000 for the past 4 years and it never did me wrong. I first got it to protect my convertible soft top (car was parked in sun 5 days a week) and it worked great. But when it rained it ran down all over my doors and made my paint oily and smeary looking. But it did not damage the finish. Anyway I ended up using it on everything. Works great on tires too - gives a nice satin finish without all the gunk like some tire dressings.

With 303 you're supposed to always wipe off the excess.

I used it on my Fit dashboard the first week i got it and I did not wipe off the excess. My window was hazing up pretty significantly for a week or two on the inside so 303 must give off fumes as well... so remember to wipe off the excess.

I haven't tried other products much so can't give any comparisons.
