Finally able to work on the car since building and getting the car on the rotisserie. Just stripping paint and undercoating. Since this was an Arizona car there is only undercoating in the wheelwells. This car is going to be a driver but I want to get all the rust out first so it won't bite me in the a#* later on. Beginning to think about an undercoating for the car. I thought I would prime it with a good gripping primer and then use Rust-olem before I apply an undercoater. Any suggestions as to what is a good undercoater I could apply over the Rust-oleum?
