I normally use tape to cover the hole. It still dries inside if I don't get to it to soon. If it does dry I make the hole bigger and shoot out the dried stuff and I'm usually good to go.
I do the wire nuts even with tape and also tape alone but I promise, if you use the new 3.0 stuff from DAP, you will have to throw away the left over within a week or two. I'm going to give these a try and hopefully will really need them as I get farther away from caulk using more and more SH!
