I only saw this stuff the other day when on ebay. I was wondering if it was any good too as it would protect the paintwork on the bottom of my front bumper from the horrible speed "mountains" i have to go over at the end of my road.
I hope someone comes forward with some experience of it
Someone on the forum has done it and it looked pretty clean although I have no idea on its durability.
