Good morning gents, my 98 definitely has some rust on it. I want to replace a lot of parts and weld a lot and have begun to do so but I have a lot of rust and I am worried about more rust before I can replace what I need too. I was going to use rust converter on everything underneath except for the motor, valves ect. Wondering if anyone has any experience in this and also can I use it on my exhaust system? My whole pipe needs to be changed but before I do that can I use that for the time being?!?! Basically I just wanna run the whole bottom with this stuff till I replace.
