Post subject:  Anyone know who May line tanks?

I finally figured I should line a couple of tanks. I don't want to mess with it myself. They are both 75 h2 tanks. One is on a bike and has a nice paint job I don't want to mess up. The other is just part of a spare set of bodywork I have. Thanks

I just totally HATE lined tanks! Why would you even do that unless they are rusted to the point of being perforated :eh: You don't even know what the future holds - I have seen a great many tanks that have had the old "sealing" come off with using the new types of fuel :roll:

The Caswell is super great stuff, and ethanol resistant. An unlined tank is just a rust hole waiting to happen......

I agree totally..lining should only really be a last desperate measure.

keyword "old". Kreem, POR 15, and the like. Caswell is a 2 part, not like the old crap............

We don't know what the future holds for fuel chemistry so the oh so good Caswell of today may become the crappy POR15 of tomorrow. Why would you want to line a good tank - it's akin to taking medicinefor an ailment you might get sometime in the future.

Not that my tank is lined, but the Caswell stuff is a version of phenolic epoxy. That seems to be used for industrial chemical tank linings, and is the most fuel-resistant coating around, from what I've read.

Because your tank WILL rust, that's a give. Either deal with it before there are holes, or after, when your paints starts bubbling. The new ethanol content now is rotting out new bike tanks in just a few years now.

I raced alcohol go-karts for years.
My class required 100% methanol and steel tanks and the top 3 were fuel checked at every race.

The big problem I've found with alcohol (as well as a drag racing buddy) is that it attacks the aluminum more than anything.
We used to run the engines on WD40 after practice or racing to coat alum. parts to cut down corrosion.
I assume that methanol and ethanol react similarly to metal.

Seems like the proper way to fix a tank with corrosion is to have it cleaned, acid etched and re-plated.
Is it that expensive to have a tank galvanized or nickel plated?

My H2 has a perfect tank but my spare has been coated.
Is there a way to really chemically remove what looks to be Kreem without abrasive media in the tank?

As far as I can see there is nothing wrong with the tanks as is. My spare is in nice shape inside. The one on the bike ended up with a lot of rust after sitting and not being used. I suppose I could try and clean it up first and see what it looks like inside. I drained it and have been letting air out for a few weeks now. Any good cleaners that won't ruin the paint I can use.
