Bedliner Gasketing (between Sheet Metal And Liner)

[neto1978]

I bought a new truck and will install a bedliner.

I don't like the idea of after a certain time have rust and debris under it on the sheet metal.

 

would Closed Cell Foam work between it?

Any advice on wich material should be better on 1/8" thick?

Depending on what your budget is, a spray-in liner will be your best choice for keeping debris out and keeping your bed from rusting. With a spray in there is no space for anything to get between the two since it's sealed.

 

I would think that even with the foam you'll still get debris and moisture under the liner and it will eventually rust.

I tried alot of things, but still get crap under it. I take two of those foam tube toy things that you use in a pool and slide them up under the liner and park on a down hill grade so the water and shit runs out the holes in the front of the bed, My drive way slopes, and spray it out a few times a year.

I would never have another drop in liner because of abrasion, rust and the swimming pool effect.

The spray in or a bed rug liner work great!

When I had my bed liner put in my 2000 silverado I had them spray rust proofing under it before installing it. I took it out last summer and there was no rust. Plus the rust proofing prevented the abrasion, mind you there are a few scratched here and there. But hey for 11 years old I have no rust under there or anywhere on the truck other then the frame for that matter.

I must agree with previous posters in that spray liners are vastly superior.

Plastic bedliners expand and contract like crazy, especially in warm sunny climes.

I would NOT recommend any spray insul. Moisture will still accumulate, but it will become stagnant - no air circulation, may exacerbate potential rust.

I am a firm believer in Line-X. Had it in my 03 by luck as the previous owner had it done and I had the dealer spray in in before I took delivery on this truck. I wouldn't own a truck that has a normal bed without it.

You can buy a thin bedliner mat, which fits under the bedliner. It is about 1/8 inch thick and will prevent abrasion between the bedliner and bottom of the bed. Truck accessory places sell it. You may still need to apply some foam camper tape in some areas such as sides of the bed, on tops of wheel wells, etc. What I hate about GM drop in bedliners is the fact that you must use self tapping screws to secure them. And the tailgate piece requires a bunch of these screws. This is a bad and cheap design from GM. I hate drilling holes into a new truck.

I have a Pendaliner in my truck, been there since new (2001) absolutely NO rust, abrasion. Dont know what you mean by swim pool effect. I am sure there are some cheap liners that can shift, expand, contract but Pendaliner is very high quality. You get what you pay for (most times).

I had a drop in, over the rail bedliner in my truck when I bought it. It was a year old when I got it. I wanted to put a cover on, so I removed the bed liner and the bed rails were scuffed, on the top as well as the outside. I ended up priming the worn areas (some of them were to bare metal) and installing plastic bed rail covers.

 

I would never get an over the rail bed liner. I have had rubber bed mats in the past which were very good. If I actually used my truck for hauling more, I would get a spray in liner.

 

My liner used plastic clips to secure it, in the holes on the stake pockets, and the tailgate was secured by the two screws that hold in the tailgate handle, and a bunch of self adhesive plastic studs. I would definitely not want to screw it into the bed.

My 1992 F150 has 190,000 miles (u can see it behind my Sierra in the picture)...most of it with a regular plastic bedliner in it. The truck is getting sold or parted out, so I lifted the liner out recently, After sweeping out the debris, I saw no rust at all. The paint is a bit scuffed up, I can see alot of gray primer, but no major rust can be found. I wish the rear wheel-wells held up so nice, they rotted out years ago. If anybody wants to keep their pick-up in showroom condition, it ain't gonna happen...that is, if u use the pick-up for what it was intended...they really aren't supposed to be "showcars" anyway.

In the early '90s, I worked part of a summer as a detailer for a Chrysler dealership (ah, those summer jobs in school...).

 

Anyway, we had a then-new-generation Dodge dually delivered per a customer's order, fully loaded (sweet truck), and he had purchased the dealer-installed bedliner. So another detailer and I were given the task of prepping the bed, which meant washing it out and then giving it a very heavy coat of wax (which we didn't bother to buff off) prior to installation of the liner. This thread makes me wonder how that held up over the years.

 

As for my own vehicles, I had a Rhino Liner installed in my previous truck, and I bought my current truck with a Line-X already sprayed in. I've been very happy with their tough, maintenance-free qualities.

 

For protection with a plastic liner, I like pm26's idea of placing a bed mat underneath...

I'd just make sure water can escape *easily*. I sold my old 82 S15 last year, which had a bedliner all those years and was really used as a truck. If you looked under it, there would always be crap, and yes... it scratched it up and there may have been a tad of light rust on a few spots (?). There no deep rust anywhere, and the bed looked otherwise new (no dents, etc). I could have taken the liner out that day and had it sprayed to look brand new. My current truck has had the GM liner since new too, and if I were to take it to have it sprayed today, it would look the same as if it had never been there.

 

My 2 cents:

 

Liner: Excellent at preventing dents, so no worry about banging things around in the bed. Scratches bed over time. They last at least 25 yrs by my experience. No real rust issues for any I've had or looked under.

 

Spray-in: Installer scratches it up really good *before* spraying it. No worry about rust after that. Slip resistant, and looks very good. No info on long term, but they have "lifetime warranties" I believe? Cost more... but not much.

 

I guess I wouldn't think twice about either causing problems over the lifetime I'd be using it.

Where can I find those? I have been looking for them but cannot seem to locate them.
