Fuel Proof Black?

[T. Cotten]

Hate to bring up and old thread, Folks,

But I have news, good and bad.

The good news is that SIG "Supercoat" gloss black is surviving admirably in this year's summer blend fuel, applied to etched glass plate and fully immersed.
It is far more resistant than VHT, and I'm switching over to it. (Unfortunately, it takes more time and solvents to load and clean an airbrush, so I must raise my flat rate.)

The bad news is that for the first time ever, well-cured JBWeld has given it up.
(I shall lay awake at night over the many times I have used it, and the many times I have endorsed it.)

Once again,.. its about the gas, not the goober.

Well, your paint discovery is great news Tom. I think all of us appreciate the effort, and time you put into these experiments, and that you share your results. Thank you.

I didn't discover it, Eric!

The interesting thing about going back to this thread is how Mr. Big picked my brain, and now wants to compete with me in the carb service business.
I guess there are even lower bottom-feeders than dumpster divers, huh.

I just discovered also that my 3 year old JB Weld repair on my gas tank has failed. I guess we have the same rotten gas here too. Rats!!!!

Bob!

The worst year for digestive fuel that I recall was 2006, when it even ate quality powdercoating.
Seasoned tank liner came out like pig's liver (attached).
But it still didn't faze JBWeld.

Fuels differ regionally, as well as seasonally and by brand. Different refineries have access to different crude "stocks". We may never know what changes occur in additives, and no way to deal with them anyway.

I guess its time I try tests with ETOH-free fuel, too.
