Monokote application
Sugarfoot,
Applying Monokote is something you can only improve on through practice. I watched the video once and have forgotten most of what it taught. The instructions that come with the film are pretty close to the best method I've found for doing wings. I tried all kinds of different ideas and came back to the method they describe. I have found the following to be key factors in getting good results from the application of film.
Temperature (get the little thermometer by 21st Century and go with the ranges suggested by the monokote instructions).
Always buy an extra roll of covering than what is suggested and don't hesitate to rip off covering and try again.
Have lots of patience and a buttload of single edge razor blades.
When covering the wing, you really have to stretch it just like the instructions say. I mean really stretch it almost to the point where the opposite end of covering lets go. And only seal around the edges. When you have gotten most of the wrinkles out, slowly run across the covering with the heat gun held about four of five inches away. It is amazing how well the covering tightens up. And if you don't like the results, rip it off and try again. It doesn't take long to get the hang of covering, and the satisfaction of the results are well worth it, I think.
Most folks are really put off by even attempting to cover a plane, and when you succeed, take pleasure in the comments you hear such as "Wow, it looks just like an ARF". At least I think that was a positive one.
Anyway... Good Luck!
P.S. - It's also helps to have a shop vac or something like that sitting next to your table so that when you are down to your last piece of covering that is just big enough to cover the wing and a small wrinkle shows up that you try to remove by lifting the covering resulting in a tear that upsets you greatly to the point that you kick the shop vac across the garage, which of course your wife witnesses and gives you a hard time about. "Oh, like we have all this money to buy a new shop vac".
Sorry, I had to get that out...
