Dunko, at the moment I'm repairing a board with a delamned bottom.
It may not be as easy as you describe.
It's fairly easy, if it's a dry glass job and the bottom sandwich has come away from the core foam cleanly. But I bet that nude doesn't have a dry glass job!!!
In this case, you'll probably find the weakest link has given way, the core foam under tension.
Here's a pic of what's in my shed.
(for anybody who thinks their bung is just for show, this could happen to your board!!!!)
As you can see, there's a lot of foam attached to the bottom sandwich, and what's left in the board is a big mess.
My approach will be to route out the damaged foam. Then replace it, in this case I think I have some 10mm closed cell blue foam, that should do the job. Re-shape it to 5mm below the rail line, then vacuum a new sandwich on.
Yep, a big job, but it should come out stronger than the original.
An alternative approach, is to just glue the old bottom back on. Some people report success with various ways of doing this, but the one I tried was far from satisfactory.
You won't know exactly what's under the sandwich until you take it off.
set a router, with the narrowest blade you have, to 3mm and see if it goes thru to the white foam underneath. if not slowly increase depth till it does, probably about 5mm, then go round the delamned area with it.
, it could be like opening a can of worms , remebering styrene foam & epoxy both have memory there could be hidden area's where the core has been sucked from the laminate, for pressure to do that much damage i would imagine there is belam elsewhere
have fun with your project hoop and hope you don't loose to much time and money in this project
