TLF glue is good, but i prefer a little more thickness. Ive tried IC Gel wih excellent results, but not everyone carries it. Was recently informed of Loctite from HD but havent tried it yet.
The Loctite gel works well. That said, the IC Gel is a bit thicker, given it the edge when you have the option

I have endless access to gloves, but dont know if i trust latex, nitrile, vinyl or other medical style gloves and its components in my tank. other commercial for fish tank ones are too bulky for fine work, imho.
I've used the nitrile lab gloves for fragging. I find the latex don't hold up as well. No tank issues from either.
