J Speer if you grind out the rust and coat with anything inluding even the strongest(3M panel adhesive) IMO the rust will again migrate under it and you will be right back to square one again.

almost 2 years ago, I sand blasted all my rusted seams, carved out the old seam sealer, and applied multiple coats of POR-15"Rust will never come back"paint. Then I used an epoxy seam sealer over that and top-coated with enamel paint.

WELLL, The rust Is already back and its becouse the Vanagons body panels "flex" and chafe against each other when you hit a bump and this causes all the epoxy seam sealer to "crack" away from the metal/treated surface. Once this happens O2 moisture and salt get back to work.

IMO If you can weld new metal in or weld a bead along the seams(to close the seams for good) I think this clould be the best solution. Sand blasting and grinding never can get deep enough in the seam to get ALL the rust and If you dont get ALL the rust it WILL come back later.

I wish I new how to weld good.
