Hi All,
Whats the best way of cutting a hole in a GRP hull? Im going to fit a holding tank ( got the Headmistresses book on order to read before I start ) and will have to cut a couple of holes.
Is it best to use a standard hole cutter? If so, whats the best speed for cutting through the GRP?
Secondly, obviously the hole will leave the edges of the GRP exposed where it passes through the hull. Do I have to treat the edges of the exposed GRP with anything, or will the sealant that I use around the skin fitting do the job?
I was going to use a silicone sealant that Ive used on ponds, marine tanks etc to seal the fitting, that seems to do the job without any drama, but if anyone knows any better then please let me know.
Any advice gratefully received,
cheers,
Ben
