This is by far too little stripping.. We did about 15-20 osmosis repairs
on various FP's and in some cases we had to go so deep that one could see what is on the other side of the hull
The hulls have to be dried for at least 3 months and in some cases vacuum heaters are to be used and the hulls should be washed with fresh waters 3-4 times.
FP doesn't have a specific procedure for the treatment, they just require the humidity measurement to be reduced at certain level. This sometimes is not fully achieved, at least on some part of the hulls, because of the chemicals added on the polymer that were used in production.
For recoating we use multi layer epoxy
barriers and lot of sandpapering. So far we never had any osmosis which came back.
I am not saying by any means that the boat was not treated properly but it's really strange to see that the boat was deemed "irreparable".
I wonder what FP had to say to this..
