Many of the R/C Forums have Threads about the different brands of film covering. Comparing features/benefits, good, bag and the ugly.
All I ever used is UltraCote and MonoKote. I consider both products a winning game for what they are being used for.
A choice one has to make for the model, and the time, plus materials used in it.
This Waco. I wish I never used film on it.
This small recovering job, I have to use UltraCote because of the color.
I've always liked UltraCote because you can remove wrinkles with heat quit easily. Or, in my case, sloppy work.
Choose wisely.
