Are there any down sides to this covering or is it as good as it appears to be ??
Leester,
I also found that the "Plus" version of Ultracote was indeed a pleasure to work with....the light tack to the back surface did make it easier to apply.
I found one "downside" to the "Plus" version, but it probably will NOT effect you. I have a Time Machine built from a Dixon kit that utilizes his "Kept-Foam" technique, i.e. a foam core wing with cap strips, rather than full sheeting. When the wing is covered, the sticky surface of the Ultracote Plus is less than a sixteenth of an inch away from the foam core. During handling of your plane, if the Ultracote Plus is pressed down in contact with the foam core IT WILL STICK, and you will have fits getting it loose again. It can be done, but it will test your patience.
There is a minor weight penalty in critical applications, due to the extra adhesive, but other than than, it is much nicer to work with than the standard Ultracote. Enjoy.
Cheers.
