Fortunately I do not have a corrosion problem yet. I just want to keep it that way. Whilst I have not had any problems with Hammerite in the past, I wonder if it could be lack of preparation. I tend to remove all loose rust, kill any solid rust with a rust killer, apply two coats of anti-rust primer, & two or three coats of Hammerite, allowing each coat to dry, but not cure. I have found that no coating will stop flaking rust. Because of my past involvement with sailing I know a little about osmosis with fiberglass. Boats stored ashore seem to suffer far less than boats stored afloat but neither as a matter of course. This is fairly obvious because the sea seldom drys out so the fiberglass is always wet. As with cars the quality of the fiberglass work varied greatly between builders. So whilst there would be some absorption of water in an H4, it would only occur whilst the fiberglass was wet. Waxoil is liquid when applied, but dries to the consistency of bacon fat ( but doesn't smell as nice) so osmosis would appear to be minimal & the coating stop any more water absorption by the fiberglass & rusting of the steel frame.. The use of Waxoil would therefore appear to be the lesser of two evils. No doubt someone with a greater knowledge of osmosis will correct me, but if the problem is not a chemical reaction Waxoil ( or it's equivalent) would seem to be the way to go.
