My truck hasn't been treated well by Michigan winters and all the salt. Rocker panels are gone on drivers side and barely intact on passengers side. Doors are just starting to rot thru the bottom in a place or two not to bad but I want to save what I have. I am looking for advice on prep work and maybe a suggestion on a stop rust primer and a under coat or bed liner type product to go over it from the body line down .
Only have 160000 on the truck and would like this project to last as many years as possible.
I have no access to any sand blasters but I am willing to put in some elbow grease on the project.
