1966 Pontiac GTO floorpans

As if I didn't take the body off the frame enough, it was removed first to blast the underside of the floorpans.  Then the car was moved into the garage and the body came off the frame again so I could paint the floors with POR-15, then Eastwood Chassis Black.  I have one hole in the front drivers floorpan about the size of a pencil eraser.
