Bubbling paint on a GRP bodied classic car

My 1974 GRP bodied classic car was perfect in summer time, and used regularly. When wet weather came in I used two car covers, one soft breathable, and one waterproof, to keep off worst of rain and bird droppings etc.

To my horror the paintwork has bubbled up badly, little humps about 3mm diameter, 1mm high.

Will my comprehensive insurance cover respray?

The problem is Osmosis, common on boats. Moisture has got behind the gel coat. Expensive specialist job to repair and definitely not covered by insurance.
