Not sure what exactly to do here. I am assembling my first kit and am working on the wings. Top side came out great. Seams close together, no bumps and straight as an arrow on the LE and TE. However, I unpinned the wing today and some of the plastic that I used to cover the plans is stuck to the bottom spar. I know I need to clean this off before I start the sheeting but don't know which is the best way. I have been using debonder with limited results. Is there any other way?
