FWIW - I have become a big fan of a product called Rust Reformer from Rustoleum. It is the only Rustoleum product I use. It seems (to me anyway) that the rest of their stuff is junk - and big $$.

I use Evaporust for bolts and small items items. They say you can use it on flat metal by keeping a paper towel soaked. I've used Rustoleum on the the inside surface of a tailgate before. It lasted 4 years without painting it and never rusted.

I used Ospho on my exhaust manifolds before painting. It did better than I expected. Read up on it. Looks like Ace Hardware has it for $27 a gallon. I put it in a spray bottle and only used about 8-10 oz to treat the manifolds. Doesn't take a lot.....just get it wet and let it do it's thing over night. Of course knock off what rust build up you can with a brush or grinder.

A local farm store used to sell a spray converter like the Rust-Oleum, it worked really well. It was rather impressive. But that place closed years ago and I haven't seen the product anywhere else. The Rust-Oleum stuff works almost as well.

X2 on the Ospho (a phosphoric acid/zinc solution). It's good stuff - even holds up in the marine environment. Be sure and rinse with plenty of fresh water prior to applying any coatings. If the zinc phosphate "crust" is allowed to remain on the surface of the base metal, the coatings won't adhere properly and will fail quickly.

I also use the POR-15 product called Metal-Ready. Same zinc/phosphate type stuff.

I just did my "spring cleaning" on my square after a long nasty winter. Lots of rust on the frame, axles, underside of the bed...

What would be best? Wire brush it to knock off the loose rust then the POR-15 Metal-Ready with a brush?

The de-icer here is so nasty it is alarming at how fast my truck is being eaten.

Prior to redoing the carpet on my '86, I removed the seat and old carpeting......and a ton of old glue. I found a patch of rust on both sides of the hump. Maybe the size of a dinner plate. It wasn't scaling or loose but I figured to address it before the carpet. I took a wire wheel to the floor, vacuumed it and then washed it down with lacquer thinner. I bought some brush on stuff from Eastwood called Rust Encapsulator and put it on pretty heavy all over the floor, actually two coats. I had also purchased some Flex Seal ( the TV stuff advertised) for another project and I put a coat down on the floors. It goes on like thick black paint and has a rubbery feel to it when it dries. The stuff from Eastwood was around $35.00 for a pint but I don't remember what the Flex Seal cost. Maybe an expensive way to address rust but I'm very confident it'll hold up well.

Well actually... no.
Encapsulator is a temporary band aid if you can't do it properly, or at least half properly (CONVERTER). The encapulated rust will continue to eat the metal and one day the whole encapsulated patch will fall out.

Sorry you missed it but the whole idea of this thread is to think about converters.
Anyway the good news is that you have bought some time before the Flintstone mod kicks in (no floorboards).

I ,too have friend who is into square bodies BIG TIME and swears by Rustoleum Rust Reformer. That's what I'm going to use based on his years of experience using it.

You may be right. We'll see. I researched the various products extensively and found a lot of people praising it. In fact, your opinion is the only thing I've read that is negative. I am confident that it'll work fine in my application.
