The starboard fixed portlight in the aft cabin of our H336 is leaking when it rains. This doesn't appear to be a standard marine part, the parts list for our boat says it was manufactured by a company called North Florida Glass. Is there a procedure for sealing or rebedding this port here anywhere? I've done various searches on every combination I can think of for "rebedding fixed ports", "fixed port leaks", etc. etc. and can't seem to find anything specific to these ports. Thanks for any help.
