I've got some extra red and black paint for Johnson and Evinrude pressure tanks. This is the Alkyd enamel from North York marine. I barely used the black, and had a 1/2 pint of the red, and used about half painting my tank. I don't have another tank project in the near future, so if you can use it, make me an offer. I've got the hardener and reducer too. I don't know about shipping chemicals, so probably best for local pick up in SE michigan.
Nothing says poor craftsmanship like wrinkles in your duct tape
