After having treated areas for rust and used KBS Self-Etch Primer, it may be some time before I am able to prepare the metal for the bodywork build and finishing coats. To stop any moisture getting into the Self-Etch primer, is there a Epoxy Sealer that you would recommend that bonds well to the Self-Etch and that will not react with its acidity ??

Cheers for any help ...

The Fusion Self-Etching Primer is not really designed to be a treatment for rust. At this point, it would be best to apply 2 coats of RustSeal.
