On the osmosis topic: this is what was done to the boat under FP warrantee. I don't see any reference to epoxy (although it may be in some of the trade names for the materials?). Does this sound like a suitable procedure?

"This treatment involved the removing of 4mm of antifoul, gelcoat and chop strand matt fibreglass which removed all osmosis blisters and 50% of the moisture in the surface laminates.

The hull was then ground using P24 grinding discs to prepare the surface and to remove any additional blisters and air voids. Over a period of 4 weeks the hull was washed 3 times to remove salt and acid with fresh water and was then left to dry for a 2 month period which achieved a below 10% average moisture content in the fibreglass.

Then all wet work was done in a shed at below 50% atmospheric moisture content and around 20oC. This involved local vinyl ester repairs to air voids. Then the hull was screeded with vinyl ester resin to fill any imperfections, 1 x 450g chop strand matt powder bound fibreglass and 620g rovings using vinyl ester resin was applied and then a layer of Deralight and vinyl ester fairing was trialed on the C.S.M using a wet on wet application.

The fairing was then left to cure and then sanded and spot filled. After a full cure of resins was achieved, approximately 350 microns of Jotun Penguard paint was applied, using airless spraying. A further 2 coats of Jotun Seaforce 90 antifoul was applied."

I don't make comments on works that others do. All I can say is that we do it differently but as long as FP has approved the work that has been done , it should be OK.
