You mentioned that there seemed to be "no adhesive" on the Ultracoat.

Not to overlook the obvious, but are you SURE you removed the bottom film on the Ultracoat?


I agree with MinnFlyer about the stiffness.

I assume the control surface moved freely before and now you feel some resistance.

As long as your servos are not fighting this resistance all the time, you should be fine.

Try deflecting the control surface and see if the servos go quite while holding the deflection. If so you should not have any problems.
