Spray on bed liner

[Sprinkletits]

I'm not entirely sure if I should be making a separate thread just for making a suggestion on building materials, but...

Has anyone thought of using spray on truck bedliner for strengthening and durability instead of fiberglass for pepakura armor? My friend and I was discussing it a while ago and he brought up the whole idea of it. It would seem to me that it's a lot safer and easier to handle/apply to the resined paper.

Any thoughts or suggestions?

Just a thought.

I've contemplated using truck bed liner for the final lining layer inside helmets, but wasn't sure how hard a coating it leaves.

A few points to consider that I don't have the answers to unfortunately, but maybe someone else does:

- When truck bed liner is applied to a rigid steel trick bed, it makes a fairly tough layer, but does it form a hard surface on its own when dries? In other words, if you apply it to a slightly flexible surface like resined paper or card stock, is it going to add strength, or is the weight of the liner going to pose a warping risk?

- If it doesn't form a rigid shell inside the helmet, you run the risk of cracking the resin on the outside over time due to flex.

- Also, not sure how sandable it is if you sand through the paper while finishing the outside.

from what i have seen on truck bed liners, is after the stuff hardens it is still too flexible, if you have ever had a piece of it by itself you will see. My recommendation si to just stick with the resin, just make sure you use proper safety precautions

I sprayed it on the grip of my AR which is made of foam mind you and it's still able to flex so I believe the answer to your question would be no

sounds like it would be good for shoe soles and the thighs on Mjolnir suits of armor.
another question i would like to throw on the table is - can it be molded, say if one chose to do a cast of a shoe sole and then poured this stuff in?
if i ever get my hands on a can of the stuff i might have to give it a go ...

Bed liner is very strong!
Now... What very strong means is a broad term so lets clarify;

Bed liner is a plastic epoxy alloy that is designed to absorb impact and prevent penetration. For those two purposes, the stuff is amazing! However, sandability, ridgidity... Not good. If you spray bed liner onto a sheet of paper and let it cure, you will be able to fold the sheet in half before it gives.

Using it for weapon grips, spartan upper thighs and other black areas as a "final texture" would be just fine, almost recomendable! For any other application, I would avoid. Unless your spraying the bed of a truck!

All of this is true. Not to beat a dead horse, but I have bed liner on my truck and the only place it's truly held up is on the inside of the engine compartment and the cabin. We went a bit overkill with it because it's just a work truck and put it everywhere it would take wear without looking unsightly. The entire bed after a few years has started to have chips come off because we use it so much. The lining is a heck of a lot better than normal paint, but the reason the liner works the way it does is because of the rubber granules mixed in with the polyurethane.

Like Cereal said, it's great for reducing impact, and it holds up better than normal paint, but it's really a far cry from resin. It simply wasn't designed for anything like this.

I tried this on foamie's and had it crack a little. Plastic-dip was better. I really wouldn't wast the money on using it on paper. If you want safer/faster just do a foam build.

ok i have had several problems with spray on bed liner because it lost pressure very fast so i went out and found a roll on bed liner and i found some that has KEVLAR in it (you know that stuff the US Army and Marines use in bullet proof vests) it worked beautifully it held up against every thing i threw at it....except the flame thrower an the 10lb sledge hammer (little cracks and that is where i decided to bring out the torch) but other than that it works great for paintball i put the muzzle to the armor point blank highest legal pressure for regulation and recreational games and for long distance snipers it held up to the test not even a scratch it took about 3-4 layers of liner to get it to that point now its just getting it up to sledge hammer proof....
