moisture wont get through f/glass (otherwise boats and surfboards would sink) so i cant see why you couldnt f/glass straight over the steel.

Not quite correct about fibreglass and moisture. Only the gelcoat (coloured surface) is non porous on a boat, hence problems with osmosis where moisture causes the glass to blister. But boats are polyester resin which is not 100% moisture proof.
However epoxy resin is water proof, but needs to be overcoated as it is not UV proof.
