I recently came across some rather large 4mm campaign signs ( 48" X 72" ) that I plan to use on my next plane. I have always used coro from Harbor sales with no bonding problems using CA. I had always thought that the campaign signs used sign vinyl over the standard coro. Upon examination of the signs, it seems that the material is somehow bonded to the coro and cannot be simply peeled off before using.

Does anyone have any experience building with this sign material?
