Hi Damon,
What you are showing here is a 'blind fix' to a delamination problem. The fixer does not know whether or not his work is actually glueing things back together or not. When you cut one of these problem area hulls open, remove the outer skin, the first thing you find is a handfull of dust, ground up faom that broke away from the outer skin. Just because you squirt some resin in under the skin doesn't guarantee you are glueing anything together except maybe a bunch of dust particles. To get the resin to flow under the outer skin, you drill shallow holes on one side of the delam area and vent holes on the opposite side. You cannot force resin in under the outer skin unless you let the air out in another position. Also this 'blind fix' method does nothing to rebond the inner skin to the under side of the foam. It is in the same condition as the bond betweem the outer skin and the outer surface of the foam. I have seen sailors attempt to fix deck delams on H16s and P16s with the 'blind fix' method but I have never seen it be successful.
Good luck,
Bill
