Path of least resistance? That would be why it will not work for repairing delaminations. You need a penetrating resin to get back into the tight crevices between the layers of glass and foam without expanding between them.
The delamination can be anywhere between the layers. At the glass to foam laminations or in the foam itself. That is why we drill down through the foam and stop at the inner layer of glass. This pierces all possible layers where the delamination may be.
Use the delamination repair method as described in the FAQ section of our forums here. It works and is easiest to do.
Here is an old cut up Hobie 14 that shows a delamination in the upper edge of the shot.
