I just got some for my ILF Morrison recurve. I wanted to use a snake skin pattern but didn't know which one would be the best looking option. I had a few conversations with Mindy and she literally done everything she could possibly to do help me. I ended up getting the ones that looked great and complimented my riser and bow. It turned out better than I had thought it would.
I don't know if you can spray on top of them. You should email and ask Mindy. She'll be able to tell you or help out in any way she can.
I have ordered their arrows wraps in the past as well and I will continue to be a customer of theirs. Onestringer is the best retailer I have ever dealt with.....period.
Try them, you'll really like 'em.
