Ethanol Induced Tank Swelling

[JohnG.]

It might be ever so slightly better, but not much. It's also possible that another 3 months by the pellet stove might help. Riding season will be here in 2-3 weeks and I just can't wait that long.

It's amazing that with all the technology available in the world, there isn't an ethanol proof plastic tank or a form of automotive grade metal immune to corrosion.

BTW,No visible issues with my Caponord's ten year old nylon tank
although lately I try to stay away from Ethanol E10-91,
it runs sweeter on straight ULP 95 or 98 anyway.

I just used it to coat a used Caponord tank that's been sitting in storage for at least 5 years at my house and who knows how long before that. It fits the frame holes perfectly and shows no signs of swelling, so now's the time to coat it. My original shows all the symptoms mentioned in this thread - swelling, holes not lining up, paint splitting, pimples on top under the paint...

The sheet rock screws did nothing to give "tooth" to the smooth inner surface, and they were a bitch to remove, so fingers crossed the stuff stays stuck to the tank. I used POR Marine Clean inside with a hot dish soap cleaning afterward. The coating looks thin and even and hard as a rock...where I can see it. But the tight bends and convoluted shapes inside make it impossible to view more than maybe 50% of the interior. It's cured now for 5 days as per Caswell's instructions, so it's going on the bike today.

I have used the same stuff on rusting metal tanks and it held up more then a decade, though it almost seems as fuel in the USA was less harsh back then.

My fingers are crossed. Should work better then hot glue :p

Like I needed that reminder...

I too have been wondering if a sealer like that will work. I hope it does! I need to look for a spare tank for my Mille so I can let it dry and do a sealer as well.
