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.
