I planned on getting some kind of spray on bed liner to put in, something like Herculiner, so I took my bedliner out only to find this:



Of course it looked worse than it does now, because I took the time to clean it and get the loose peices out of the bed. Anywho, does anyone have any ideas what to do about it? Or is there a treatment I could put on? (bedsides a chemical bath) OR could I just spray the bedliner on top of it?

thats a bedliner for you

plastic drop in liners suck, i pulled mine the minute i got my truck...i would say sand it down, maybe use an acid etch...and then hit it with some sort of rust killer paint, may por15...then put the herculiner over that...

POR 15 is the big rave people here and on some of the other forums stand by this product a buddy of mine uses it on all sorts of metal loves the stuff only complaint is it fades in sun light

it might make a good base coat then spray on bead lines after.

That's why I have a plastic bedliner, to keep stuff in the bed from falling through the rust holes

well, im not a rust repair expert, so i wont offer advice to you on how to fix it, except grind it down and git rid of it!

The reason im posting is for those who have plastic bed liners. If you need a bed liner like i do but cant afford a sprayed in one, get yourself some hub grease, for repacking wheel bearings and smear it alllll over your bed after you take out the bed liner and clean it. then reinstall the bed liner and viola! not a big deal anymore. maybe a little messy, but a heck of a lot better than having a rotted bed.

your bed rusted thru because of that plastic liner. lol.

I wish the whole truck was made out of bedliner!

The herculiner stuff looks promising, and you don't really need to get the kit. All it comes with is a paintbrush, rollers, and an abraisive pad. Just get the gallon of stuff and it says that that's all it takes for a 6' bed. I think I'm going to find some of that por 15 stuff and do what 91tpu and cymon were suggesting.

I might go ahead and coat about 50-75% of the cab and outside of the truckbed......May put a hefty dent in my wallet but I think it would be worth it!

I just heruclined my interior. So far so good on that.

91TPU

i plan on doing this also, could you please take pictures of it, and tell me how your prepped...i have read a lot, but since you just did it you might have some good stuff for me to know fresh in your mind.

ooooooOOOOOOOOoooooo......That would be cool!!

Alright no problem. The biggest PITA is definately removing the sound/heat plating on the floor. Then it takes a hand grinder with a wire wheel, then I used the herculiner scuff pad, and finally washed it down with acetone REALLY good.
Your gonna need 3 coats to get it all really good:

A base which you'll be able to see the paint of the floor through.

Then a second coat to cover all the paint

And finally a touch up for the spots you missed or that you just couldnt see in the previous light.

I still need to do coat 3...

i was actually just planning on leaving the sound deaderner/plating...i dont feel like removing it since the truck is gonna get sold soon anyway.

Remove the bed. sandblast/wirewheel, por15, and repaint the frame. Build a flatbed at your local autocraft facility, they should have welders available. Powdercoat your new bed........................................... thats my plan.

Im dreading taking off my plastic liner.
Im going to go with line-x later this year. I can see rust all down my bed if I pull the top parts away from the bed.

If you really want to fix rust, the only way is to cut it out and weld in new metal. It's mostly flat, so grab your MIG and have at it.

Stomis

I'm not so sure it will stick to that. I got some on my plastic pieces by my back seats and its peeling right off.


As for the bed I would take a good hand grinder wire wheel to it. Por15 it then herculine it. I have seen Por 15 stop cancer rot right in its tracks.

ran out and pulled the bedliner myself--not a speck of rust. and it's original equipment, at least that's what the guy told me when i bought it. maybe it's the dryness out here??? it's never been garaged.
side note--among other things, i build a lot of kilns. outdoor stuff, raw steel clad, fiber insulated. i let them rust and paint with rust-mort. it seals the rust from further oxidation, much like corten steel. can be painted. handles the heat at 2K+. not necessarily suggesting it for the bed with a roll on liner, just throwing it out there.
