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?
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!
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.
