Tank liner removal

[almarconi]

There isnt any pictures of MY tank posted... That other tank pictured is someone elses.

Chuck..I realize that is not your tank. My only point was that the tank that the member posted is still too rusty to use in my opinion.

To remove Kreem coating your best bet is soaking the tank in acetone or paint stripper and using the rocks. If you are not worried about the paint you could take it to a radiator shop and have them remove the coating. My only concern would be why they used Kreem in the first place. If it was used to seal holes in the tank then removing the coating will cause the tank to leak. Once you remove the coating you will know pretty quickly if the tank leaks or not.

Its all gonna be repainted, so thats not an issue. And i am aware of the possible holes. Thats the thing about buying and its been coated and you dont have a clear answer as to "why"..I was on the Kreem website and they claim you can reapply over the existing liner if needed. I just really need to be 100% sure every aspect and detail has been fully dealt with before its painted... One little mistake in prep and the gas will eventually ruin the new paint if it leaks thru..

I would get rid of the kreem all together. Best to have a tank with no liner it. Try the acetone and aquarium rocks. If you really pressed for time or don't feel like fooling with the acetone, take it to a radiator shop and have them clean it out.

On a '78 GS1000 fuel tank that's easier said than done. it's hard to find one that's not rusty inside. I suspect it's because of the metal they used to make them.

I used paint thinner and expansion plugs.
Let it soak, periodically turning for about a week.
No more liner..

I've stripped three tanks and have posted extensively about this subject in threads now in the archives.

Paint stripper is the best to soften the old liner, and MEK is second best. Physical abrasion is also needed to scrub the metal and sharp edged aquarium rocks are the best thing I've found - they work much better than screws, ball bearings, nuts, chain, etc. because they are small and able to cover the entire tank.

Ed, I'm curious. have you tried stripping a liner out with a caustic solution yet? (by boiling it in the solution))

Never tried that Dale. Two of the three tanks I stripped had decent paint jobs on them and I didn't want to strip them completely.

OK...I went and got a gallon of MEK which the Kreem site says to remove the old liner. Before i make the metal covers for the sending unit and petcock holes, I have a question. Should i remove the rubber seals around the sending unit or leave them so the cover will seal? Anyone that has had actual experience with the MEK and the gaskets please expound on my quandry. AND...I was wondering about the effects on the plastic on the gas cap.

[chuck hahn]

Just found that MEK is a plastics " welder" type solvent..but i cant find any info on its effects on rubber gaskets.

[chuck hahn]

I threw an old rubber gromet into the MEK overnight and there wasnt any dterioration or anything...just some really clean gromet when i took it out.

MEK is working extremely well on the old liner. Melting it like butter setting in the sun. Large sheets of it already have peeled away and the hemos will fish them out easily. Once its all cleaned out its off to Larry for the painting. Skunk 2 will be done in about a month.
