Anyone ever remove a tank lining?

[SDBuckeye]

Hi,
I am trying to get a radiator shop urethane coating out of the inside of my tank in order to re-line it with POR-15. The folks at POR-15 recommended POR Strip with a chain to get out the old stuff. This is looking like an impossible task. Do I need to kick it up a notch and use aircraft stripper? Maybe I should just bag it and spray it down with rust converter?

Thanks for your help!

Cheers,
Lyle

Ed, I should have just searched all of your threads! I did search here and google, but couldn't find much that was focused on urethane.

Maybe I will get some MEK, as that seems to be a notch stronger than POR Strip.

Lyle,

Get some high strength paint stripper, the stuff that requires paint thinner to remove. Plus some aquarium rocks. The photos below should give you some ideas on how to plug the various tank openings. Also, when the stripper is cooking make sure you vent the tank or the pressure build up can damage the tank (don't ask me how I know).

Ed...and make sure when you pull out a plug to vent that you've covered it with a rag, so as to prevent it from spraying out. Don't ask me how I know.....

Yea, the chemical reaction during the stripping job builds up pressure. A little pressure is okay but not too much.

Stripping an old liner out, and derusting there after, is a pretty hellish task but certainly doable. Please read though those old threads and learn from my mistakes.
