I like the white rustolium lacquer for painting the back 7 inches of the arrow. I usually just use 1 or 2 coats, and it goes on nice and smooth. Much much cheaper than wraps (and doesn’t add the unwanted tail weight for you UFOC types). It’s good to rough up the shafts with some steel wool first.
I’ve used tape and fletch-tite glue. Both worked fine. I have to add, Tape sure is easy.
