Actually I bought it at my LHS and is packaged as a plan protector. Not sure of the brand. It came in a roll that I used to cut off just the amount I needed. Most of the wing released, and most of the problem was around where the two balsa spars and the servo mounts are located. (It's a SIG Something Extra) Since it is my first kit, and the first wing section that I have built, it's probably mostly my fault for over using the CA, but still need to clean it off.
