Sanding floor pans Sucks

I did POR-15 on my floorboards when I got the car. They were actually in pretty good shape and still had pretty good paint on them, but I wanted it sealed better, especially since I know old cars don't always seal that well. Just pulled the carpets the other day for my trans swap and the floor still looked brand new 3 years later. Didn't look like there were any spots lifting or anything, seemed like a good solid bond, even where I had to grind it down for the tunnel mods.
