TANK LINER REMOVAL
« on: March 04, 2019, 11:41:05 AM »
Hi all,
          As title I have a tank that has been lined, this must have been more than 30 yrs ago as the bike was taken off the road in 1983.
This is now coming off and looks to be clear ish light brown so not sure what/which brand it was.
I have tried various chemicals on it but no luck Acetone, Thinners, Starchem paint remover and nothing will touch it.
Also talked to a couple of dip and strip companies but they will not guarantee their dipping chemical will work.
I have also talked to a local company I use for powder coating they have a dipping tank to remove old powder coat and he has tried a couple of times with tanks he has and it did not remove it.
So just wondering if anyone has a miracle cure to get the bloody stuff out.

The US site recommends MEK (Methyl Ethyl Ketone)(nasty stuff...read the warnings), but maybe that's already been tried.
I have a pristine tank with a very poor Kreem liner. Someday I'm going to have a go with acetone on that.

Plumbing supplies for plastic pipe joint chemicals should get you a convenient supply of mek solvent to try and dissolve a sample.

Yes, as with any flamms,  I'd do that outside to reduce risk of inhalation and combustion problems  ;D

Another to try if that doesn't touch it, you can readily buy methanol from model rc nitro-motor suppliers.

MEK is not to be Fu**ed with - but it should get the liner out.

How much in a tank James do the fumes work in it as well as the liquid !

I got some MEK on eBay from Switzerland to remove the paint from the inside of my CB750's bearing journals, after recommendations on here. You can't get it in the EU, apparently, because  it has killed people with the fumes. It worked a treat but I also bought a mask and goggles.

As far as liners go, my 750 tank had a blister from petrol getting though a small pinhole, so Menno removed the old failed liner with an acid bath dip and applied a new one, which also subsequently failed.

Analysis shows that the new liner had reacted with traces of the old one, which had survived in the original hole. The solution ended up being a new tank from Silvers, surprisingly good value (and quality) and no more grief.

I used some at work back in the eighties and almost fell off a 20 feet stand under a wing, I don't remember what happened but didn't mind as I became quite spaced out! Can you imagine that happening nowadays!

Its readily available in this country and widely used in industry as a solvent /cleaner. Plumbers use it all the time on plastic pipework. Use sensibly as you would Acetone or any such like and you will be ok. I would think it will remove your liner. You might have to leave it in while. Some of your rubber seals might not like it. I've worked with it most of my working life. Use in a well ventilated area.

You shouldn't actually shove your nose in the can. Its not the wisest of moves. I've seen it done many times." Cor that stinks" then they pick it up and sniff it. Usually followed by "#@%$ me!!! what's that."
