Finally time to do something with the rust along the bottom of the doors and like the bedliner along the rocker guard that some of you have done. Question is, after I sand and strip everything what brand of bedliner did you use (rustoeum, Herculiner, duplicolor etc) and how well is it holding up?

Thanks,
Oren

 

might wanna search this one...its been asked a few dozen times, I used herculiner on the bed and rockers...its held up pretty great and covered body repairs I did with fiberglass and epoxy which I'm amazed has held up awesome for almost three years now...
just remember to used a motorized wire brush bit for a drill to grind up the bed paint good...otherwise the herc wont stick well.

 

Used Herc as well, on my ranch hand bumper, my rockers, my bed and eventually my tool box.

 

The doors rust from the inside along the bottom seam. If the seam is still intact, what I did was pop off the inner door panel spray some galvanizing compound inside the door along the lower seam, then topped that with a light coat of oil foam/spray. That should keep the rust at bay and prevent it from continuing to rust underneath the liner.

 

I ground out as much of the rusted lower door as I could...then used two part tube epoxy from harbor freight to fill it in and file to reshape it (I used like 20 tube kits which prevented me from rshing the job or wasting product since it kicks all at once )... I used "rust-zero" on the lower inside of the door at the seam and replaced the lower window weatherstripping.... It has shown no evidence of new rust since doing this I honestly didnt expect it to hold up so well 3 years later..

 

Wouldn't something like a rust inhibitor be better than oi? I would think that would create an adhesion problem for the liner.

 

that what I used...sprayed the green converter liquid stuff on everything before applying the zero-rust which is basically commercial por-15

 

Disclaimer: I'm not a body guy.

To clarify, I used PBlaster Corrosion Stop on the inside of the door seam (in addition to a 1st layer of galvanizing paint (weldable rust inhibitor)) since water will collect there. It will never rust again. I did that after stripping & applying primer/liner to the outside.

That's on a door where the metal is intact, light rust, no holes.

My passenger door had a fist sized hole all the way through inner & outer panels. I chopped the whole lower 10 inches off with a grinder, bought a welder on craigslist and stuck some new metal on. Someday I'll get around to posting pics of that job.

 

That makes more sense.

Gosh I am glad that I do not have to worry about rust. All they spread on teh road here is sand. And it doesn't snow here very often. Course most flatlanders here can't drive on it anyway......Doesn't do squat for traction, but at least I do not have to worry about rust issues.

I feel for you guys in coastal areas AND have ice and snow, and the salt from both of those to deal with.

 

The PO of my truck used Wal-mart rubberized undercoating along the bottom of my rig. It has already started wearing off (he did no prep) and discolors more and more each time I give the truck a bath (twice in the four months I've owned it).

POR15 is the right way to do it. It's expensive, but it's a multi-step process and it works.

For me and my beater, I'll stick to roll or spray on and just keep a thick layer on it.
