Por 15 gas tank sealer

[EScanlon]

I don't know of many products that can withstand constant immersion in MEK. That's one of the main components in paint stripper. I've seen epoxy products, fiberglass resins, and many "impermeable" paints lifted off or softened irreparably by MEK.

Don't know about POR's properties with 100% ethanol, but do know that when I researched it that was one of my questions regarding the percentages of ethanol in gas and what they would do to it and was informed that it would be no problem.

The bottom line regarding which product to use, Redkote or POR may boil down to whether you pay someone to do it, or do it yourself.

I did the POR 15 treatment on my Z's tank almost three years ago and it is holding up fine so far. It was a lot of work to do it, but the results are worth it. My Z was stored for years with very little fuel in the tank and it had surface rust on the entire inside of the tank. What was below the fuel level was all varnish and nasty flaky crud. I used muriatic acid first with several lengths of chain in the tank to get the majority of the rust and gunk out. I then did the POR 15 kit EXACTLY per the directions. It was a long, backbreaking process, but I would make the same decision again. Highly recommended.
