Rust Bullet? POR15?

My cruiser is rust free, but I am about to tackle some body work on my old WILLYS flatfender CJ2A. It is primered gray, and has had rust problems in the past. Now I see some ruct starting to stain the primer.

I am going to replace the floors and a couple pieces on the lower body panels, and will strip off a lot of the paint down to the metal. I was thinking of pulling the tub, stripping it, and then rust coating it before I paint it.

Wondering if any of you have used Rust Bullet for this purpose... basically to rust proof the entire tub and other body parts before painting. Any issues? Results?

I did the entire floor in my FJ55 with RustBullet. It goes on in two coats, and is rediculously hard when cured. Like so hard that if you paint over a bolt, it will not come out. Even a grinder has a hard time going through it. If you brush it on, the finish is not terribly smooth, but good enough for an underside. I have heard of people thinning it and spraying it through a HVLP gun. I ended up Herculining over mine, so the finish wasnt terribly important. Hope this helps, Hodag.
