I just took up my carpet bc I had a leak. The floor is in real good shape for its age and has mostly only surface rust. I went to the parts store and they recommended bedliner to put on the floor for protection. Is this a good idea? Has anyone else done it? Can you recommend somethning else or is this what most people does?

I would think anything that stops rust would be a good choice.Some bedliner coatings are sprayed with special guns and some are rolled on. Someone who has done this would be able to give better advice then my 2 cents...

I know they sells coating material in aerosal cans. Maybe POR-15 (??) would work but I would see what other people say. I have a leak somewhere on my passenger side. The floor area is soaking wet. I see just a little bit of surface rust on my floorpan too. I was reading through my Helms manual yesterday and saw a section about factory metal treatment to stop rust. It said not to put anything on the floorpan over the catalytic converter (raised bump area on passenger side). I would be careful with what you put on this area as it gets really hot. Stock carpet on this section has no foam padding.

i would have a look at your upper frame just under the windshield, there may be a rusty spot where rain is soaking through.
What the worker recommended to me was indeed a spray aerosol can application.I am going to first make sure that the leak has been sealed then I will seal the floor. Any help that can be given would be great, thanks.

I believe por-15 only adheres well to major rust. What Im thinking of doing with my floor pans is sanding down the surface rust and the spraying it with rubberized undercoat. It comes in a spray can.

for the rest of the unrusted floor you just need to ruff up the paint/metal. it will not adhere to paint. POR 15 is meant for heavily rusted items. I am about to try Rust bullet once i get my floor pan cut and replaced.

so por-15 no good for me? i don't have major rust only surface from what i can tell i was thinking about using bedliner.

I may be wrong here but I thought Por-15 was more of a rust preventer. I have heard that you need to clean the rust as good as you can before applying Por-15. And you can brush it on. Again, I may be wrong but I think Por-15 would be a good product for what you are doing once you get the rust cleaned up. Better than bedliner.

I have used brush on POR 15 on the inside floor of every convert I have ever owned that I replaced carpet - it does not have to be on rust to adhere, prep by sanding or otherwise roughing and apply heavily - it forms a very hard surface and you can paint over it if you want to

I'd prep all the exposed floor and hit it with por-15 or Rustoleum. Just something to seal the surface and prevent further rust.
