I have been plying with them, since I received them. it appears as if the product is PVC.. so.. It may not handle screen goo very well. This means a thick coating is out of the question. However, it may be possible to put on a very light, highly thinned coating of the product. (CRT Screen goo?) This would work fine, I suspect. i am doing a few sample things tomorrow. I will see if I can work them into the schedule.
