Restore it, Dont part it!
I saw a video where a guy was working on a customer's truck and the truck when new was coated in por 15 or some other undercoating products and from a distance it looked like it was doing its job but he discovered that it was rusting under the coating bad! Like the floors where gone. Iirc he was replacing brake lines and the brackets where even rusted in half the whole truck was rotten because of this coating it was just holding in the moisture under the coating. And this was like a 10 year old truck (farily new to me) and I was a lost cause.Also please don't use those products.. you hit the nail on the head without maybe realizing it... do you know what activates those products? moisture..... They were made to coat oil rigs out in the ocean so need to cure in a wet environment. What the professional restoration guys on the SPI site will share is there experiences with vehicles that they knocked the POR off and the metal under was gone. It absorbs moisture to dry then traps that moisture against the metal and it continues to rust. There will be proponents of POR and those type products saying the metal was not prepped correct. My argument is if you spend the time to remove all the rust to prep it right then all you really need after that is epoxy primer anyway.
