The rustoleum is a temporary fix until I get some sheet metal to weld in. Once that is done I am looking at using a rust converter/remover and spray the whole tub inside and underneath then paint it again. That's why I was looking for rubber flooring at this time so I can remove it when I fix the few small spots that have rust in them. Have 1 hole in drivers floor pan about 4 inch circle and surface rust on the step in the back seat.

Thanks
