Wrong alcohol. you need denatured not isopropyl which contains water.

You also must limit alcohol to less than 5%.

As far as the glass is concerned, 8 OZ is little more than sealing
tape.

At a minimum, you need a couple of layers of 17 OZ, double bias glass.

Leaving wood unglassed is asking for trouble which you seem to have
found.

Time to break out your right angle sander/grinder with some 24 grit
and take everything back to bare wood, then reglass making sure you
seal all wood with glass.

If that is more work than it's worth, probably time for a new boat.

Have fun.
