Update, I pulled the hot glue plug out of the above tube of caulk tonight because I needed to seal up an outdoor light. Still is good 2 years later.

Good tip. Better than plugging it with a tapered dowel. As I used to do until I saw this tip! One point though, are there no adverse chemical reactions between the hot glue & the Caulk / sealant, etc?

Not to my knowledge. Beats the old screws I used to use.

wirenuts also can work. twist overopen end. they come in different sizes and sometimes it helps to have a little caulk coming out to help secure it.
