Correct, we've tightened up the rail a couple of years ago. still finding butyl blobs occasionally inside the boat. I used the poly caulk along the toerail and the deck, so don't think it even touched the butyl. We left it to cure for a month (boat was stored indoors). BTW I could get the loctite here only sika and or quikcrete ...welcome to Canada. The reason I brought it up is that after it cured it still reacted with the interlux brightside - it was supposed to be paintable... However, Seems to have solved the drips we used to get when it was raining hard. But we had a little water come in when we raced last week (rail happened to be in the water occasionally? so next step is to use the washable marker idea that was suggested, and see if we can ID the exact location and try and tighten a bit more. If there is anything left to tighten...
Has anybody ever removed the toerail etc and redone the butyl? It has to be a huge job - probably too much trouble for the few drips we are getting so far? Thanks for all the good suggestions.
