Thanks for the information.
I don’t have any big areas of damage to warrant the making of a mould, but it’s a useful description of the procedure should it happen. Mine are small areas, particularly the steps on the bathing platform which have taken a few knocks from the passarelle and other objects being brought aboard.
I have ground these out and attempted to recreate the non slip pattern by dripping wavy lines of gel coat. My artistic skills need more development!
All the best
