One time I had a detail done, and the product used lasted near forever. It was matte, and while it looked like the tires were coated (BFG All terrain so lots of sidewall), they never turned brown.
After sitting a long while, they would pick up some pollen or dust. The coating had a slight adhesive property to it... But nothing severe.
Ive used 303 but it always seems to me that it washes off, fwiw.
