We have an IP 380 hull #60. During heavy rains water begins to drip from the forward ceiling light in the aft state room. We have checked everything that we can think of including rebedding the fuel
and waste deck fittings. When removing the light fixture we find a solid amount of what appears to be 5200. Either IP puts it there during construction or the previous owners were attemptng to fix the problem. Can anyone recommend a solution?
