I repaired a large area (15 ft2) area on a boat that got bruised by a stand and had damaged core, but only minor damage to either skin.
* Popped it out and repaired the damage to the outer skin. Very minor, just a little grinding and laminating. Easy to fair.
* Stripped the core from the inside and vacuum-bagged new core and inner skin. Not fair as glass, but about like original and hidden under the floor (but open for inspection). Fortunatly there were no bulkheads in the area (which, of course, is why it dented--incorrect blocking by the yard).
I used the boat hard for another 12 years and then sold her. Never a hint of a stress crack through the paint. Probably took about 15 hours of labor and $200 in material. The insurance gave me a check for $5,000!
Core replacement is not difficult. It takes good FRP skills and a plan. I was lucky in that the damage was under the bottom paint and I did not ave to match topsides; that is the labor intensive part, to me, unless you are refinishing the boat anyway. Of course, if the alternative is scrap, a quick coat of pain below the rail is not so hard.
