had an area of rust on the floorboard to this extent. Not bad at all and only bubbled through the first layer of paint, but since I do not plan on doing a full resto for a few years, I want it sealed. I am also going back to the black rubber mat that this truck had originally. I want to be confident that once I lay the mat down the rust has stopped growing. This is the only rust this truck has, but I want to treat it now (and correctly) so I won't see more in a few years.
POR-15? Eastwood's 3 part frame resto system? Any help would be appreciated. Sorry, it may be a no brainer question, but I wanted to ask the experts.
Thank you!!
