Hi;
I know this has been discussed and I've read the threads. I just want to make sure I've got it right.

I have a base covering on the wings in yellow Monokote, (new stuff), and want to apply a "sunburst" pattern in Flame Red Ultracote, (I have it already). My understanding is I can't use the "Windex" method, right? If not, what are my chances of applying the Ultra over the Mono and not getting a real bubble mess?

If I can Windex, any tips?
Thanks all!

No, you can't use windex to apply Ultracoat. Windex only works with applying monokote because the ammonia in the windex activates the adhesive in the monokote, but the adhesive in Ultracoat is different and won't activate. To apply Ultracoat over Monokote you will need to use heat to apply it.

And to avoid bubbles, remove the underlying MonoKote. Just leave enough for about a 3/8" overlap

If you're really uncomfortable doing that, at leasy punch a few bazillion holes in the MK where the UC will be covering it so the air has an escape route

This is over an open structure, (wing ribs), and I was hoping to avoid the tediousness of piecing this thing together on glass or something. Any other suggestions? How 'bout starting with low heat to get the pattern down and progressing up in heat? Still the same results? It's been a very long time since I've built a kit and I seem to have forgotten some stuff.
Thanks Mike!

I did something similar with the bottom of my Sig Somthin Extra wings. Cut out squares, added each piece individually and tacked down the edges on the rib caps then hit the middle with a little heat in the middle to tighten things up. Just be careful you don't heat it too much as they will shrink away from the edges.

seal the edges with clear finger nail polish

I did my GP Cap-232 with a white Monokote base and red and blue Ultracoat for trim and stripes on bottom of the wings. it worked great. Just turn the iron low enough so the Ultracoat sticks but isn't so hot that it affects the Monokote. Here's a picture before I added the cowl.
