I have now used the spray protectant twice on my tires. This is the first time..ever..that I really didn't NEED to redo my tires 1 week later! This is a remarkable product. If the tires are really clean, I just spray this stuff on and leave it alone ..for at least a half hour. Then a lite rubdown with and old towel...man!! It turns my tires black, and the wipe down removes the shine..just leaves a low level sheen. The amazing part is...it lasts!! When I went to wash the car Saturday..I always start with the rims and tires...I gathered all my stuff...went to spray down the tirres with GPC..and what do you know???...they still look great!!! Of course I did them anyway, but I am very impressed with this stuff on tires. ..however..only if you like that low, level, black sheen..look:xyxthumbs
