Hello; Yes, I did take the backing off the ulttracote, I also vacuumed the wood before I tried to stick anything to it.

Thanks for all the good suggestions, this will be more then 20th kit I have built and covdered, and have never had so much trouble. I went out and bought a roll of white monokote to finish it off. I used a roll of clear monokote to cover the wing, that worked like I remember.
