RE: How to STOP a rusting Fuel Tank

Steve, I've use a product called Corroseal, which is a water based product that theoretically chemically converts the rust into a stable molecule that you can the paint over.* If it were me, I would use Awlgrip 545 primer over the Corroseal, after letting the Corroseal cure for a couple of days.* If you don't see reoccurance of the rust, then I'd coat over the 545 primer with your choice of colors of top coat.* This seems to work on exterior spots I get on a steel hull, so perhaps it would work for you.

Hope that helps.
