I'm planning out the body work for my K5. I've been researching which would be a good undercoat. People talk about Her, or duriliner what else is out there and what have you guys used?
 
I went with the liner xtreeme from www.sprayonbedliners.info
It's a damn good price for a catalyzed liner and it seems to be holding up very well. I also did the very top section of my tailgate that's outside all the time on the k5. And it still looks great and not all faded.

Once you mix it all together you get 3 gallons of liner... I used half of it on my tub and tailgate. Still have the other half.

Very good customer service too.

Adam,

How do you like the texture? Would it be ok for bare feet? Which of their guns did you use?

Sorry for the hijack :D, but this stuff looks like a great product and I am getting ready to spray my tub too.

I like the texture. Would be fine on bare feet. You could just not mix the crumb stuff in and make it smooth if ya want. My buddy bought a nice undercoat gun that we use a lot. An ATD one

Do you think it would also work as a undercoat? Most of my damage started underneath.


Idk. I think only if you could really get all the gunk off. I'd use some nasty kinda sticky stuff on the bottom of a rig personally. If this stuff isn't applied to a good clean scuffed surface I can see it peeling. Then you get water in it and it holds it and eats it worse...

Too bad, I'll have to keep researching. Very nice looking job!

I'd definitely do the interior with it though.

In all honesty a goopy crust of dirt and oil mix on the undercarriage is the best. My frame by leaky old motor was spotless under the gunk....
 
You can definitely use a bed liner type material as "under coating", but, like Adam said, it's got to be CLEAN before shooting it. Not just power washed or even steam cleaned, but physically scuffed, every square inch. I know this as I've shot both my K5 and a 53 Willys wagon I'm building using AL's liner (which I highly recommend). In both cases the bodies were off and the ideal scenario is having a lift. I did the K5 on my back and the Willys was done on my lift. I personally would not attempt it if the body was still one a frame.

My K5 was rust free and I still have somewhere in the neighborhood of 20+ hours in prepping the underside (I can be a little anal though:D ). I used 2 gallons on both of the rigs I've done and am very happy with the results.

The AL's is a very nice product, you can customize the color to your liking, texture can be changed with air pressure of the gun, seems very durable and if done per instructions adheres very well.


Oh, there are pics in my K5 thread and there is a thread on the Willys inn the driveway also with some pics.
 
After seeing the results of the xtreeme liner... I would put It on any rig top or bottom if prepped right. It's just so damn hard to properly prep the undercarriage of any rig
 
Yeah it seems like a chancy project. Once I get the K5 back and strip out the interior, I will see just how much rot/rust there is. I will patch and replace all the rot and then shift to work on the underbody. I thought a rubberized undercoat would seal and protect the Zero rust I plan on painting the underneath. But now I am not sure. I might instead paint several layers of Zero Rust and another top coat of something else.
 
I recommend the Ryoken system:

1. Piss coat of zinc
2. Urethane primer
3. Urethane top coat
4. Then do your Lizard Skin or rubberized uncoating or whatever


For my undercoating I modified his system a bit as my frame was not clean enough to apply zinc to:
1. Rust converter
2. Urethane Primer
3. Eastwood 2K Urethane Chassis Black
 
Info

I'm a novice at this, so bear with me. If I replace the rot, patch, whatever, then clean and remove the flaky rust. I could use a rust converter, then a primer and then some kind of rubbercoat? I know nothing is a permanent fix to rust, but I would like to put it off for awhile.

Recommend a top coat before the rubberized undercoating. Also the paints I'm talking about are two part catalized paints that are sprayed through a gun, not the Home Depot rustolium special.

I just hope Ryoken chimes in to clearify...

Don't you have to sand the two part paint before going to a second coat?
 
Rust

No not between coats. Between primer and base coat, maybe. It depends on the paint.


What's a good Rust converter? The only one I've ever used was Rustoleum's, which they sold at my last job by the gallon. It worked pretty good, but was nearly $100 a gallon.

I'm not sure what brand is best. I used Eastwood's rust converter and got good results but I just put it on. I can't speak for its longevity.
