I want to cover a wing with a pattern similar to that pictured with profilm. Normally I would do this by covering the whole wing in the base color and then use PROTRIM to add the markings, but in this case the markings are 50% of the wing so is there are a better way of doing it in this case, but still using profilm/protrim?

What about making it out of individual pieces of proFILM, maybe tacking them together before applying to the wing? Although this could be tricky.

Cheers,

Never used protrim before. I have used monokote on sucha project though. I used a nice size mirror, layed out all parts then seemed the pieces together using heat. the film is easily removed from the mirror. we have been able to do some outlandish styles this way.

If I were covering that wing, I would cover it completely with the darker color and then very carefully iron on white stripes from the trailing edge forward.

I'm not familiar with Profilm but this is how I would do it with Ultracote or Monokote.

First cover the wing from the spar to the trailing edge with white. Then cover from the spar to the leading edge with purple. Then add purple rectangles over the white to achieve the pattern you want.

I'm not a big fan of prejoining pieces and then applying them as a whole sheet to the wing. I tried this with Ultracote and got a little too carried away with the heat gun...result: one seam pulled apart so I stripped the wing and recovered.

I understand how you feel but I have had very good results from the prejoined method. You have to at least overlap the edges (dark on top) by 1/4 inche then use a very hot setting on the mirror. You want it so hot that it actually sticks to the mirrored surface. Seems won't come loose if you have a good bond on the mirror.

If you are using Monokote that technique works well. After doing a bit of research I found out that Profilm is actually Oracover, Oracover (Ultracote) shrinks too much at too low a heat setting to make this technique work well. The seams pull apart much more readily then they would with Monokote. Since it is indeed Oracover, it will be easy to put trim over a base color because it's adhesive won't gas and make alot of bubbles like Monokote would.

I second Mendes' suggestion, especially if this on an open bay wing with no balsa sheeting forward of spar. Drum-tight Monocote adds a lot of strength to the wing. Plus it is a lot easier to do IMHO. The additional sq. in.'s used vs. piecing together is negligible.
