Yeah I tried the sandwich method, worked great for the most part. I used some crystalite or something like that from Home Depot. It was only $13 for a piece to cover at least 34X18 with plenty to spare. It cut like butter, but when I trimmed it, it crack due to the lack of support. (My fault) I might re-do the cp with lexan but I don't want to. My biggest problem is the artwork around the trackball, instead of folding the excess underneath I cut it and it doesn't look that great. Oh well, an expensive lesson learned.
