RE: fletching painted or dipped arrows
Depends on a few things. First make sure you get quality spray paint. Krylon worked best for me. Next, let the paint dry for a couple of days.Even with the fast drying paint. The paint on the outside may feel drybut the layers underneath are still drying. I tried fletching within 12 hours after painting and had less than favorable results. Third, buy a good quality glue. Some glues like Bohning Fletch-Tite and the Platinum eat into the paint. I use Goat Tuff and haven't had any problems. Fourth, make sure after the paint has dried to clean it with a clean cloth. Don't touch the paint or the fletching contact area with your fingers. Fifth, let the fletching dry overnight before you shoot.
I have sold a ton of arrows done this way and have only had a few come back with vanes coming off. And that was probably due to my carelessness in prepping.
Good luck to ya.
