Nah, I only do it if my slicks have been unused for awhile. And I let it sit on there a couple of hours before I take the car there. Put a nice coating on if you do it. You dont have to drench it but make sure its even coveragedo you do that before every outing at the track?
can this be used on radial tires also ! if so how do you prep ! spray on let soak then repeat !diesel fuel, acetone, mineral spirits, turpentine and mix.... thats what we used on out go kart tires and could drop 25 points on the durometer
