To anyone who said FJ40’s rust from the inside out, word. I’ve decided against using paint through primer on the internal overlapping areas. Figured it’s best to have the whole tub acid dipped prior to paint. Logic is that the acid bath will dissolve any rust I can’t get to. It will create a little more void allowing a zinc phosphate dip to internally coat everything. I’ll still use an internal frame style paint application to get paint where I can. So… Anyone done a zinc phosphate dip on their tub prior to paint? Any advice or recommendations?
Some photo examples. Driver seatbelt mount, just the inner plate is replaced. I should be able to get the outer skin done this weekend. Thicker gauge steel and ugly welds but I’m leaving them thick for reinforcement.
