Been there, done that. Best to rip it all up and redo it. Balsa core is relatively cheap and easy to cut and if you do the job right, it won't get wet again.

Wow, thanks guys for the info, general concensus is to remove the top layer I guess.I was looking for an easy fix but I guess if its worth doing I might as well do it right. Gonna try a small patch with the dremel tool first before I get too carried away as working with fibre glass is new to me,{always had ferrocrette yachts before this}.
Once again thanks for the info guys.Cheers Paul

It is a miniature circular saw - 4.375" inch blade, very thin. Cuts through FRG easy and clean. Being small it is easy to deal with but you need to not overfeed it. One of my favorite tools onboard.

If you're cutting fibreglass with any kind of power tool, make sure to wear a mask of some kind - the glass particles are bad for your lungs.

Very definitely and also a paper "moon suit" with taped cuffs at the wrists and ankles. See my post #6 where I misspelled the word "tape". Gloves also help, the thin kind. Anything that involves cutting or grinding FRG liberates copious amounts of tiny fiberglass hairs that penetrate into any exposed part of your anatomy.

OK that's the same critter I use. A small circular saw with a thin kerf blade. Just never heard it refered to as a slitting saw, wondered if you knew of some fabulous tool I never heard of. Try a diamond abrasive blade in it for cutting glass. Big step forward and cheaper than a carbide tipped blade too....
