Thanks, Rob. I found a few online that gave me options I want to try. I'll look at these, too, and see if they have provide any better solutions than what I'm thinking so far.
I was so proud of the flush hatches on my stripper. Even got the front one waterproof after 18 months of fiddling. I’m now removing the magnets after big rusting problems. Even resetting them in more epoxy didn’t help. I’ll try internal cross bars tightened with a bolt and external nut.
Hans were you magnets coated and were they a 3 layer coating Epoxy+Copper+Nickel ? I tried magnets with my last build and so far I have not had issues. I am just wondering what others have experienced and if the coating material has made a difference.
I plan on removing the webbing tie downs (overlapping hatches) on the hatches of the VJ and changing them to flush mount using magnets. Has anyone tried using lacquer to coat the magnets?
My experience with lacquer on furniture is that it doesn't stand up well to moisture. Set a damp glass on a piece of fine lacquered woodwork and you'll have to repair a nasty "water ring" mark.
I have no expectation it would be a good sealant to protect against rust in a damp environment.
On the other hand, I have used epoxy covered magnets in mixing some nasty chemicals for years. Until the epoxy wears away with years of spinning, the magnets are very well protected ( and chemically inert ).
If you have any epoxy around, I'd suggest you go with that. Use at least two coats.

Black epoxy coated magnets
I used these epoxy coated magnets on my Guillemot build years ago. They have held up well.

Robert,
I used magnets like these, I only have one season on them but they have held up well so far. http://www.magnet4less.com/product_info.php?cPath=1_123&products_id=660
Lacquer-coated magnets--maybe not
