Pearl Drums, is POOPY a word? Hahaha
I wouldn't use a pattern, if I were to have the skin look I would use real skins. Just makes sense to me. Are you wanting to put it under the glass to protect the skins? If so I would think that alot of these longbow guys that use them would be able to tell you what you can spray on top of them. KennyM, Apex Predator and Dmaxshawn do alot of longbows, you might ask one of them. They are some great guys and very helpful.
