[C320-list] Chasing Leaks, yes starting that convo

Rainey day was today for sure. Was able to see that pretty much all my porthole windows are leaking and seem to have a more serious leak from around the propane container. So looks like butyl tape, 4600, and 5200 are in my future. Also, I may have a leak from one of the standing rigging mounts just above the starboard seating area. Appreciate all the ideas, was able to look closely in a lot of the places mentioned above and confirm or discount areas that need attention.

I have also had leaks at the main cabin portals (Still trying to solve a stubborn one of those with new gasket and o-rings). Main cabin hatch (Now solved with new gasket and smoked plastic that was cracked). Emergency tiller cover (Solved with bytle ). Pedestal (Pedestal currently removed and off getting re-coated) let you know on that one. Had a slow leak in the aft cabin slow dripping down aft cabin back wall. I also placed paper towels in Port aft locker just front of the rudder trunk before it goes under the aft cabin. That covers the whole backside. Also agree try being inside in a good solid rain. Good luck.
