Windex (ammonia) does not activate Ultracote. Xylene does, however, I have not used this type of method with Ultracote. Instead, I use @BalsaDust ’s glass method and layout the ultracote on the glass and heat them together. Peel off glass, then apply to airframe.
I agree windex does not work on Ultracote. Even if Xylene does work please do not use it is really bad stuff it will kill you quick.
