It visually looks bad, but from what I can tell it's just almost or all surface rust.......just a lot of it. Main problem areas are the rear axle housing and the hitch. From the axle forward everything is pretty much rust free. My main concern even living in AZ is I just don't want this to get worse. I'd love if appearance wise it looked more like an AZ truck though too. I did take a hammer to it a few minutes ago, and it scrapes off pretty easy just a thin layer of actual rust. I did buy some POR-15 kit a while back, but never got around to trying itCan you post some pictures of the areas in question? I may be able to help you without having to physically look at the vehicle. My shop is at CaveCreek and Hatcher though if you wanted to swing by for me to take a quick look at it. Thinking that we can help you without actually spending any money at my shop for heavy duty repairs. I have a few tricks for rust abatement.
Rust-Oleum 300112 Rust Dissolver Gel, 32 oz Amazon product
Spray it on and walk away. Smoke two cigarettes, this should take 15 minutes.
Wash off with water then dry with compressed air immediately. Scuff the freshly cleaned area with grey scotch rite then coat as required. I like to use spray max 3680102 trim black as it holds up well but it’s like $20 per can.
On the cheap you can use the rust-oleum epoxy appliance paint. Holds up well but takes a while to dry. 5 thinner to medium coats will do ya well. Use tinfoil to mask off the areas you don’t want overspray on.
