Yes, either too much lube or a lube that isn't thinned properly will really slow down drying time. Glad you have things going your way now. You may still want to try a small fan, it really accelerates drying time.
I must have lucked up. My BLL seems to dry very nicely. I did notice some slight tackiness on the third coating that I tried on my 311-188 Hunter boolits. I may have added a bit too much on this third coating. They did eventually dry however.
One coat ought to do it unless you're sizing, then just wave the bottle at the container for the first coat to get something on the bands (three drops for 100 bullets or so), then size, then coat with a little more.
