POR 15 and rust rehab

What do you guys think of the stuff? I have some holes on my TJ that need attention and I've heard some great things about POR 15. My jeep has the cancer in they typical spots and I plan on fixing it this summer. My fix doesn't have to be perfect because any of the bad spots I'm going to hide under body armor, but I'd at least like to halt or slow down the spread. Any thoughts you guys have would be great!

Are you talking about using POR 15 on body panels? It is more useful on the frame but I suppose it would work on the underside of the body panels. Best way with the body is to cut out and weld in new. I had a bad spot on the right rear next to the tailgate. I cut out all the bad, welded in a piece of steel, then coated everything inside and out with Rust Converter then covered it with body armor. Looks good. POR 15 worked terrific on the frame and underside. Just cover every square inch of exposed skin some way because it is REALL tough to get off!

Hit the rust with a steel brush to loosen and remove the flakey crusty rust. Then paint it on there.

I used it on one of my highway salting trucks at work. The dump body had some cancer spots popping up. 1 year later you can tell the spots that got POR15'd and the few spots that were missed.

POR-15 is awesome but it has no UV protection so it must be top coated if being left exposed but will work just fine under body armor. Brush it on and it'll dry smooth and the rust will be stopped dead in it's tracks.

I have rust in a couple of places that seem like they are going to be really tough to get to... Yesterday I was feeling around in front of the rear wheels and it was like I popped right through a weakened membrane, the second I touched it a pile of rusty flakes fell out onto the pavement. I have a lot of work ahead of me this summer... I live in Buffalo where the city has a love affair with salt. Once I get this done, my Jeep is going to live at the carwash this winter.
