I have a sand blasted rust free floor pan and want to coat it with something to prevent future rust. The Jimmy does not have a top but will have carpeting (someday). What coating is recommended?

Rust Bullet or POR15

I use Rust Bullet. I'm happy with the results. You do have to use two coats, one to encapsulate the rust & the other to seal the first coat from moisture. Never used POR15 .

i used rust bullet, im happy, never used por 15 though
Never used R/B but POR 'wants' rust, if your covering bare metal then you need to use a primer coat.
Gotta think R/B would be similar.
POR is not UV resistant either, needs a top coat if exposed.
I'd check the R/B for that too.
I'd try a search, been a lot of previous talk about this subject.

I've searches but it seems everyone is covering up rust. I have very little rust on the truck but I'm sandblasting anyway to get rid of the cheapass paint on it. I've had the truck for 20 years and don't plan on getting rid of it anytime soon.

I am the opposite of above never used rust bullet but did use POR15. I used it on my gas tank and skid plate for the tank. After 3 years both are still a great finish. I did blast the skid and sanded on the tank till I got a clean metal to start with.
I also used the POR kit after having it in my garage for over 4 years. Its not recommended to store it like that but worked for me. I bought the kit to redo the floor pan, but instead replaced it in sections.
I did my rear diff comver in it also

If you do not have rust now, the recommended method is to use self-etching primer on the bare metal, then go over that with an epoxy sealer, scuff that then paint. Most any of the coatings for rust do nothing when rust is not present. They work off of a chemical reaction between the iron oxide and the active chemical in the coating. I use a liquid rust converter (phosphoric acid, IIRC) on what little rust I cross. I put it on the rust, it goes to work immediately. When it gets on the non-rusted surrounding metal it does nothing except waste money. I think you would be best served to do the self etch with an epoxy sealer because once the coatings for rust are dry, they will not prevent rust.
Just my $.02.

That makes sense. I just assumed that they protected against future rust. I'll look into that tonight when and if I ever get out of work.
With the 3" of rain we get a year and 1" of snow every 5 years rust isn't a big problem. I was more concerned with a wet carpet sitting on floor. I want the carpet to reduce the heat from the floor boards and firewall. This time of year life is good 70 degree days, 50 degree nights but the 110+ in the summer sucks.
