Undercoating
I scored a really nice 2008 short bed in SC the same color as my truck to replace my bed that's getting a little cancer and I want to treat it before putting it on. It's got just a little surface rust but I've done a little reading and saw that Eastwood now sell a rust encapsulating rubberized paint. Does anybody have any experience with this stuff? I've used their plain encapsulating paint before and was pleased with it. It IS expensive but I don't mind to get what I'm paying for. I'm wondering how many cans I should order? I want to treat the frame while I'm in there too and wonder if I should just use some rustoleum on the undercarriage.
Also, I've got a set of bed bolts to go back in but no nut plates. These buggers aren't cheap either at $50/set of 8 from ebay. I'm contemplating just tacking some nuts to the frame??
Anybody in need of a very patchable short bed??

The only rubberized paint I have heard of is PlastiDip. I have never used it, but honestly just thought about trying to coat my under body with it a few days ago. I haven't pulled the trigger yet though. If you look it up apparently you can peel it off in sheets after it is dried if you wish to remove it. Maybe someone with some experience will chime in here because I am interested also.

I sprayed Chassis Saver on mine with pretty good results. The only places it has chipped off were my fault for not spending enough time on prep work. I do plan on pulling my bed this summer and really cleaning up the frame and suspension and giving it another shot. You'll want to use two coats to make sure you completely isolate the metal from oxygen. I used satin black, which looks factory. It is pretty expensive but you get what you pay for.

Chassis Saver is legitimate stuff, an alternative to POR-15. If you make the effort to prep things properly and give it a good coat (brush or spray, either way), it should last for many years.

POR-15 would not be a good choice. I have used it to coat floor pans. It is not UV stable, so anywhere direct or indirect sunlight hits it, it will deteriorate. The manufacturer recommends a topcoat if used in an external application.

I used a oil based rust primer, then coated the frame with that new bed liner paint from Rustoleum @ $40 a gal...and its all failing after a year.
Heard folks have good luck with the expensive POR, even though it needs a topcoat.
My Mercedes has thick, real rubber (with fibers) undercoating...this is probably what we should be using, how do we make this?

I will say, POR-15 done right is amazing stuff. I was playing with some years ago and did the full 3 step process on an EXTREMELY rusty machete blade which has since seen some very heavy summer time firewood use and held up extremely well.
I wish I were motivated enough to do that to my truck- but then that would mean virtually a complete chassis strip.

I used Rust Bullet on my frame 3 years ago and top coated it with Eastwood Chassis Black and it still looks great.

Redford, the topcoat is only necessary if it needs to stay shiny and pretty instead of the color fading over time where sunlight hits it. It does not mean the paint itself is breaking down.

I have seen some amazing things with POR the key is the prep before you put it on. You can top coat it with black tractor paint which is cheap and will keep the POR from deteriorating. I'd doing this to my frame and bed in a few weeks im starting to acquire all the parts to do it now, and a little POR goes a long way. My buddies dad said he painted an entire frame and part of the underside of one of his classic cars with only a quart! Also depends on how this you go with it as well.
