I didn't know where I should post this so I apologize if it's in the wrong place. This is a 2004 T4R Sr5. I realize the part that covers the gas tank is bad but I was more concerned with the frame.
It doesn't look "bad" yet, but it might qualify as concerning. Hit it with a hammer, scrape it with a big screwdriver, if you can knock pieces off or hear a thud instead of a ringing, it's bad. Don't just check where you can see it easy, either, the worst spots will be anywhere dirt collects and soaks up water.
I really don't have the tools to hose it down thoroughly and then blow dry it with air. Could I take it to my mechanic or is going to krown rustproofing an option? If not, I could take it to car wash and pressure wash the undercarriage then use the Eastwood coating when it dries.
Also, the black stuff you see in the second pic does flake off when I scape it. Is this what you are referring to?
I just purchased this truck and I love everything about it so I want to fix this issue ASAP. It's been giving me sleepless nights because I don't want to feel like I've been had. Thank you for the suggestions.
