All of the sealers im aware of are 2 pack epoxy fibreglass kits.The problem isn the epoxy , its the fact that they DO NOT stick to the inside of polythene petrol tanks. They'll look like they are sticking for a few months , then they'll peel off and bubble. There is no rough key inside the tank for it to stick to.I know i sound a bit pessimistic but its only because ive been round the block on this problem.

The only solution is to fit the sealer and then drain down after EACH ride . It works for me.

There is a moisture cure urethane sealer called POR-15 which I prefer over the epoxies for steel tanks. It requires the rust be removed before application.

Having been in the painting trade for 30+ years the Caswell recommendation to just cover up the rust with the sealer goes against my grain.

You are correct about the epoxy not sticking to polyethylene. Caswell even states that on their site.
