Before installing my new windows, I drilled out and sealed ALL the old screw holes with Epoxy
. Then I drilled new holes and used butyl tape to seal the windows and screws.
All the deadlights I installed earlier have not leaked. I pulled and replaced my NEW portholes with similar deadlights using butyl tape.
It's supposed to rain tomorrow, so I will be able to check for any new leaks
then. Wish me luck!
