Default Methyl ethyl ketone for rubberized undercoating/bedliner removal?

Is this my best bet?

I had my most aggressive options between mek and xylol.

Are these too aggressive? I was planning on trying the mek after dinner tonight.

I want to strip the unirail to put frame stiffeners on the xj. It is the rubberized undercoating.

Im betting mek would take off rubberized undercoating. Doubt it would take off quality bedliner. Mabey take off herc or rustoleum bedliner.

I used to have a can of something called strypeze. It was way old, 70s vintage.
It would remove almost any coating. Stuff was nasty! Doubt u can buy something that effective any more.

I did read somewhere that the quality bedliners use xylol... but I didn't feel like paying $15/qt

Where did you get MEK?
I've only been able to find its replacement.

This is the best bet. Nothing lingering. And you don't need to spend big money for chemicals. I've done a couple this way.

A torch and putty knife would work for the thick stuff and then use a wire wheel.

If using MEK or Xylol, do it outside and even then use a respirator and gloves that will resist the chemicals you are using. MEK is some nasty stuff.

Already planned for. I was at least going to do a test patch

No dice. Would probably be better if I could soak it. Plans to pick up wire wheels and grinding discs tomorrow

Last night I was stripping off some of the sealant/filler used on the seams inside my TJ tub so I could do some welding. This stuff is much thicker and at least as tough as most undercoatings I've encountered. The wire wheel on my angle grinder buzzed through it no problem. Hand scraping the few areas I couldn't access with the grinder was not fun

What kind of grinding where'll did you use. I was going to try a flap wheel first, after I knock off what I can with wire wheels.

It all seems easily accessible

Ah sorry, I thought I said wire wheel but I guess I bricked on that one. Wire wheel all the way, a flap disc will just melt it, clog, and fling molten rubber all over the place. Wire wheel does quick work....still messy, but at least it's effective too.

I'll do it outside

Picked up a really stiff bristled cup wheel, cleaned up way better than anticipated. Plan on cleaning it up again later in the week to weld stiffeners in Saturday.

I was expecting a horror show for some reason.

I use a kerosene heated power washer for spray on undercoat.
