+Chris Kilmer You could use Butyl for this but I think my preferred choice would be Polysulfied. The owner had the Dow 795 left over from the portlights and it works well. I am not a huge fan of butyl as it is hard to work with and tends to keep oozing out and does not like high temps from the sun. If you do use it make sure you get a good quality. Thanks for watching and I am glad you can get something form the videos.
I would have liked to hear the ultrasonic test after the fix. I have used a car radio, with treble boost,the bass cut and volume loud, to test for leaks around windshields using a rubber tube as a stethoscope. Tune the radio in between stations on FM and listen for the noise. Good fix. You can use the ultrasonic detector for lots of other diagnostic jobs as well, especially listening for leaking valves in an engine, compressor or a gas pressure line.
+BChrisL Never heard of the radio thing but guess it could work. And yes I do use the leak detector for more than just finding deck leaks. I did not think to go back and retest but after 6 years the hatch is still not leaking. Thanks for the comments and ideas.
+Wayne Canning thanks for the reply. I wanted to hear the test when it was sealed. I'm working on a Bristol 29, trying to bring her back to better days, so I am taking notes, especially with regards to sealants and other materials.
+BChrisL I am sort of thinking on doing a full video on locating leaks and if I do I will be sure to do a before and after with ultra sonic. You do make a good point it would be interesting to hear without a leak . Thanks
+Paul Wyand No particular reason, epoxy could have been used. This was not a structural part but more of a trim filler so the sealant should be fine. But yes epoxy would have worked as well. Thanks
+boat buddy I have retired form boat building per say however I have been wanting to do a video at a boat builders shop and hopefully one day I will get to do this to show the process. Thanks for watching and the comments
