Gas Tank Paint Dissolved

[gypsmjim]

My Winter project was to restore a vintage OMC metal tank. On the first fillup the gauge gasket failed, gas seeped out and the paint was destroyed. Is there a aerosol can gas tank paint that is gas resistant?

North York Marine sells an alkyd enamel aerosol paint that is gas-resistant, including the OMC red for their vintage fuel tanks. See at:

That was the paint that I used. The gas leak was discovered after only one overnight leak.

Never had that problem with NY’s paint before. Did you also use his primer paint? Also, how long did you let the paint cure before you put the tank into use?

Its best to leave a gap in the paint around the gas
cap. Mumbles should have an example of what this

I would recommend adding a "hardener" to the paint to aid in its ability to resist the fuel. This does not mean you can let fuel just sit there, but it will allow you time to clean up spills before damage is done

To be fuel proof, you want to use a two part urethane paint as found on your vehicle or an epoxy paint.

Being in a hurry, I never masked the top of the fuel filler properly on this Johnson JW tank and I paid the price as the mix got under the paint. The paint shouldn’t have lifted or bubbled the way it did. Thanks for the reminder Tubs!

Other than that – It’s a fabulous paint job . . . 😎

Thanks Garry. Yeah, it was kinda cute except for that one flaw. Here you can see where it wasn’t masked on the filler. Funny thing about it, after sitting for a few days, the fuel mix must have gassed off as the paint bubble settled down and could barely be seen.

There are some very good epoxy spray paints available. In Canada, Canadian Tire sells a selection of heat and chemical resistant rattle cans from VHT and Duplicor that work very well. I have used them on fuel tanks and my 1951 Chevy exhaust manifold with excellent results. Of course, the colours are limited. Red, black, silver, etc.
