There are some companies making a track spray where you spray on your quarters and rubber is supposed to fall right off. I think Griots has it. Not sure about crack sealer but would be a good test. I had an Acura TL once and it had to go to the dealer. I picked it up and drove like it had a flat. I got out and they had parked on top of where the parking lot cracks were fixed and a piece of that the size of my hand was stuck to the tire. It was a mess. Thats when I noticed they leaned over the fender and it had a dent in the top!!!

Last time I went to the track I sprayed fluid film on my quarters and the rubber wiped right off.

That's a look that's earned & I like it. :D

Even Mopars can do it!!! :3gears:

Wd40 works before and after

I’ll second that, works like a charm!
