Bedliner Removal

Hey guys I'm trying to get all the paint and coatings off of my cj tub to see what metal needs to be replaced. Ive attacked it with sanders and beer...the paint comes off easy enough, but bodyliner was used on the inside of the tub, and that stuff just won't come out...today, I went after it with a sand blaster, and got basically nowhere in 4 hours.


What is the best way to get the bedliner off of my tub??

I used a needle scaler for the most part and a wire cup. Worked pretty good, but be careful the needle scaler will also show you where the metal needs replaced.

Fourwheeler did a "what works best" write up about 6 months or so ago and I believe aircraft stripper worked the best. Lay it on thick and let it sit.

Heres a link to some of the info

Using chemicals will be very messy. I had it on the underside of my tub. Found that using an air chisel with a flat end worked really well. Just have to be careful to keep chisel flat enough so it does not ding the metal, just removed the liner.

I used one of these. Worked great on the under coating.

Bedliner is a 100% polyurethane, 100% polyurea, or a hybrid of both. Particles are sometimes included, some are rubber.

This stuff is tough with excellent adhesion, so you will need to get rough to remove it mechanically.

Polyurethane dos not soften when heated, but it can burn which produces carbon monoxide and hydrogen cyanide, in addition to nitrogen oxides, isocyanates, and other toxic products. So trying to burn it off could go badly wrong.

If you want to use chemicals little touches it as it is inert but methylene chloride is good at removal. Also known as Dichloromethane (DCM), Methylene Dichloride and Methane Dichloride. it is bad stuff!!!

Best way is to mechanically take it off and use a face mask (easy to find now) and goggles. Then have a paint system ready to kill residual rust and prime.

I have the same job ahead of me, not looking forward to it. I plan on trying a coarse wire wheel like CJoffroad used. Apparently the PO thought bedliner is a cure for rust.

Rust is one of the few things that will lift bedliner!!!!

I can see the attraction of bedliner in a cargo bed which sees a lot of action and no rubber mat but in a small utility Jeep it is harder to justify. I put rubber floor mats.

I think it would be great for an undercoating if used right, otherwise I agree. Save it for the truck beds.



After reading this thread I saw a couple of videos of people using citrus strip and covering it with plastic for about a day. Looks like that might work pretty good.

Good old fashioned methylene chloride paint remover with good ventilation is the only thing that will work or the needle scaler someone else mentioned.
Depending on what type of liner was used, DIY vs sprayed in polyurea Line-x/Rhino type, sanding or sand blasting will have varied results. The fact that you tried blasting with little results shows that it's probably not a DIY product in there or your blaster didn't have enough muscle behind it

This one is still in step one

Then step two

Let the scraping begin after it cools some.

It may come off EZer if some of the heat is retained.
