It is not hard at all to remove, I messed one wheel up (got a couple of drips) and was able to peel right off. Good tip on the use of the cards but you can spray the tire and peel the stuff off. Also use a large trash bag behind the rim to protect hub and brake parts. You don't need to remove the wheel. As far as durability, I feel it will last, more importantly, it gives a layer of protection to the wheel. Also- touch up is quite easy if chips, just spray chipped area!Brilliant!
Now, how hard is it to remove the dip, especially from between the spokes of LSS wheels?
