Has anyone used this product? If so what is the outcome as far as quality goes? I asked my Line-X guy if he could coat my wheel wells and he suggested this product.

 

Are you talking about this stuff, by SEM?

I'm curious, too, if anyone has tried this stuff in wheel wells. From some quick searching it sounds like you need to scuff up the surface a little (400 grit sandpaper), which I might not mind doing lightly in a wheel well.

 

It might work good for your wheel wells, but I wouldn't use it on the body. The guy that had my truck before me had the bottom of the fenders, doors, and bed sides done and the paint just fell off of it. It coulda been because the prep work wasn't done right, I'm not sure but I just had it all taken off and repainted.
