bedliner for floor pans

Has anyone used bed liner for their floor pans? Does it have decent rust inhibiting properties?

Actually don't use it, if I could delete this post I would

I'd go with POR-15. Some people talk trash about it but I think most failures of POR-15 come down to not following the directions. They even have a very simple "cheat sheet" that they call "directions for people that don't like to read directions"

I had similar surface rust on my 3500HD project; I knocked all the loose stuff out with a wire cup brush on my drill, then painted almost the entire cab interior. I did the engine side of the firewall too, as it was formerly a diesel and the insulation pad that was there had caused a little surface rust. Plus, the truck was getting painted black afterwards...







Just please...please...read the instructions carefully before you use it. It's nasty stuff. But, not nasty like bedliner!

Thanks someotherguy, good idea with the POR. I have used POR on the truck (and drag car etc) so far but I find it sticks better to sandblasted/bare surfaces.
I found when I even used the tie coat etc (when applying it over existing paint) it ends up peeling off. I might just wire brush the bad areas and "spot paint" the POR. I don't want to strip the floor. The floor also has some various drill holes that I will weld in patches as well...
Maybe just paint the floor white again..

According to them (I'm sure you already know this) bare metal isn't their ideal surface, which is why I just gave the floor the wire brush cup treatment. I never saw any peeling from any surface I applied it to, and that includes the entire frame of that truck. The frame had lost every bit of its original coating and had heavy surface rust. I took it to the car wash and blasted it with degreaser, then wire brushed the large sections with a wheel and whatever crevices I reasonably could get to by hand with a brush.



I didn't do those couple crossmembers you can see at the rear of the frame since they were slated to be removed for the wrecker unit install later. I had the truck for about 2.5 years and no peeling anywhere. It went to Ohio after that and I lost track of it.

Catylized bedliner is going to be no different than a catalyized paint. It will give off some fumes for 30-90 days until cured.
a paint without a hardener would be a bigger concern since it will resoften and give off fumes when hearted.
Either way, covering something up is not the ideal solution. POR fits a need but view it as slowing down the problem not eliminating it.

Yep, I did the same in terms of wire brushing (using air tools etc) and the POR started to peel in some spots. I also must say that I didn't use the necessary "top coat" to prevent UV rays so perhaps that is why it peeled.. I guess overall it will still protect the frame etc. The POR painted surfaces (on my truck) were also exposed to the elements than my race car which I sits indoors mostly

Yeah, that's a lot of bare metal, clean-ish, vs. the heavy surface rust that was on mine. They probably would have recommended you started with their metal prep product to etch the metal.

Yep, I actually did use the metal ready as well..oh well it probably is doing a better job than your standard Rustoleum/Tremclad (what the brand name is in Canada)..
In this video I have some footage of the freshly painted POR areas..

I was planning on using Rustoleum spray on bedliner for my truck. I dont have bad rust issues but there are spots I want to touch up. I got the "professional" grade paint+primer stuff that claims to stop rust. My floor pan is very clean, but there are just spots I dont like the look of
