So I am looking for ways to minimize rust building up on things like bumpers, tire carriers, axles etc. This is about a year of having this sand blasted entirely and coated with primer and bed liner. I am probably going to see about having all this stuff stripped again and redo it, but I was wondering if I should look into a better base coating? On the inside of my tub I used silver Chassis Saver, then self etching primer, then the bed liner and it is holding up great. What are some suggestions people have to stop these things from rusting, especially at bolted joints
