Below the waterline was coated in grey anti-foul in a good sound
condition. Twelve small areas of anti-foul were removed and the underlying
surface examined. This was found to be the original gel coat and primer.
Strange, maybe I am am not understanding ... but ...

When new gelcoat is applied over the existing one, you do not use any primer. You clean/degreese the hull well, then sand the existing gelcoat to get better adhesion, and then finaly clean it with an acetone, and "paint" the hull with new gelcoat.

In the defective area where the blue layer separated, is the white gelcoat still shiny?
