I used it a long time ago. Make sure whatever surface you are applying it too is clean!!! And use the metal prep that is comes with, because it needs something to grip onto or it will flake! Thats what happened to me. I also put the POR down, then topcoated it with just a gloss black.
As far as how it stands up to driving and a beating, I dont know, it was on the car while I pushed it up and down my driveway for fun.
