New body old body fixup

Rustoleum doesn't really do much, or even last imo. I'd treat underneath with some Por-15. I'm not sure if they have it in a spray can, but you do brush it on. Converts the rust.

For what its worth, here's my story on an '02 Tahoe, 18 years, 220k miles of Michigan salt: we have rust and plenty of it. While the previous posts focus on the panels, the underbody is important to consider. My husband and sons do most of our maintenance but we have a shop to take care of bodywork. Those guys understand this Tahoe is not a beauty pagent contestant, and selectively use these less expensive fenders noted in this thread, as well as weld patches, quick spot work, etc, whatever makes sense. These panels have been perfect, sidenote.

While the cosmetics are good, the underbody is another matter. For example, last year we ran all new fuel and brake lines. We will tow light loads but not our 7000 pound boat, nope. We can see the shop does some remedial rust work underneath, but they say we are approaching the EOL for this truck. We would have to go under the truck and meticulously treat the rust in nooks and crannies. Not practical- everyone busy, and we don't have a lift. Who's gonna crawl under there to scrape off rust and spray rustoleum? Since the mechanicals are sound, we believe this more limited use of the Tahoe is safe. It's a great ride - smooth and nimble, looks great, super useful.

So I guess my tips are: check your lines, try to keep up with the undercarriage, do what makes sense for the cosmetics, and enjoy!!

I've heard por-15 works good, not sure about the corroseal. What is it?
