If you go to forums that feature older cars with rust, you will see that practically EVERYONE who is restoring a rusty car uses POR15 unless they are welding in new replacement panels. Whether it is really permanent, I don't know; most restorers use the stuff and then they never really look again to report.

My brother-in-law used it (or something similar) when he restored his 1970 Boss 302 Mustang, but like I said, since he never checks it, I dunno how well it has protected the panel ever since he applied it in 1984. But it is fascinating to watch it turn rusty steel into a hard black crust. I would ask except it was the floor boards and he'd have to take out the interior to check which I don't think he would be willing to do...

I used that on the backside of the chrome bumper on my old school mini truck and 10 years later it's the only part of the truck that hasn't rusted.

I have used it on all my projects and still do. Through the years it's been 10 cars and 6 trucks. Just used it to treat the inside of my Norton Commando fuel tank. Good stuff.

Then we have a go.... Fender meet por-15. Lol

Any evidence of it flaking off? I used the Kreem system to clean and coat the tank on my FZR600 but I have doubts that the "rubber bladder" coating will last forever. I am especially concerned that somehow the coating will get damaged and the tank will rust again...

I bought a used Miata once bottom of the car sight unseen. When I saw it the rust was mindblowing. Must have been in a flood? I used that stuff on it bit by bit until all was better. I had the car five years and the rust was beaten into submission...

None. I can tell you that POR 15 is the tool of choice for tank coatings now that we have to deal with ethanol. Apparently all the other coatings are affected by Ethanol over time. Some quicker than others. With the Norton, those were primarily manufactured with fiberglass tanks then coated. The ethanol is raising havoc with that coating and the fiberglass resins. The rebuild of my Norton constituted the use of a custom built metal tank and the builders pick was and is POR 15 for it and all the others he repairs and/or builds.

Used it to line the tank of my 78 GL1000 Goldwing. No flaking and it's constantly in contact with gasoline.

We have a lot of people use gear oil (use) it is thick, it is not. When the sun warms the body and the oil is distributed in all the cracks, such as oily film even on rusty surfaces.
But it's internal processing.
There is one drawback. You can stain your clothes for the first time. But it's not expensive and reliable way. Oil never dries, and will protect the metal from the water.

I've used it before, but I only had it on the car for 2-3 years, worked well when i got rid of it. No beef at all, definitely recommend it.
