Rust underneath gas door
Ok so there should be a recall on this **** it makes me mad my spot gets bigger every year and it imperfects the truck. Is there a recall? Every other one of our body styles I see in Ohio has the typical rust underneath the gas door. End of the rant.

Yep. wheelwells too. I thought about getting it fixed, but now both rears and both fronts are rusting.
So much for my shiny baby. I've shopped for a replacement, but the prices!

Eff it, I'll get a car for a DD and keep this for when I need a truck. It runs great!
Just do like I did. Remove the door and shroud, sand it, hit it with rust stop that forms a polymer base, paint it with color matched paint and clearcoat, put it all back together. No more rust.

Does anyone have any insight as to why it rust at the gas door? I understand wheel wells get pounded with dirt rocks salt etc, but the gas door area puzzles me. I have a flareside, so fiberglass obviously doesn't rust, but I see many of our trucks with this issue. Is it because when gasoline spills out of there on occasion it removes wax? weakening paints tolerance to the elements? Just curious

My, very, non-scientific guess is that it's a combo of issues.
One being water and salts mixing underneath it and being sprayed towards it, since it's open to the world under the truck.
Two being the gasoline fumes and other spills weakening the clear coat.
Three being that the plastic throat that the fuel tank sits in pushes against the fuel door during operation, causing the door to make contact with the body, which creates a voided space for water to get into and start rusting from underneath.
Probably more that last one than any of the others, but they're all probably contributing factors.
I live in an area where they use a lot of salt and brine. I don't have any of the fuel door rust or wheel well rust. I keep a think layer of wax on the inner lip of the fuel door, never drip fuel on it and always wash on the top of the wheel wells (accessible from when looking up under the read r bumper) weekly during the winter.
