Oh, My! The 5 min is great for everything BUT the thread! You need a rod finish for that. There are many different ones out there. The rod finish takes 2-6 hours to set to where it isn't sagging which is why folks have turners or dryers. A turner puts the sag to work letting things level. As the rod turns, the finish is trying to find the low spot and in the process smooths out beautifully.

I use Flex-Coat. There are others.
