Thanks chaps for your all your replies regarding the foam rubber on boat stands and painted boats sticking to them.
I managed to get hold of some black felt, doubled it over so it's about 1/8" thick and fixed it to the stand with a smalll screw in a cup washer well away from the hull so no glue or solvents anywhere neer the boat. So far it's all ok.
I can't take credit for it being my idea but hope anyone with the same problem can do the same to avoid disapointment.
I knew I could rely on you guys to come up with the solution, thank goodness we have the forum.
Regards to all
Mike.
