POR 15, any expierenced users?

I used POR extensively on a Corvette I'm restoring. To relate to your specific questions:

1)I used it to cover both sides of newly installed floor pans. Scuffed them with scotchbrite pads and painted. Seems to be holding up fine.

2) Used the leftover paint to cover my metal work bench. I ran a wire wheel over it first to strip paint an knock the scale off some rust. No other prep and there was still a lot of paint still left on it. The POR has held up great to six years of abuse (it is a workbench!) and has only lifted in a few places due to letting chemicals puddle and sit.
