Here's my bit..

I'm quite fond of the glass method as described above. I've created a few 'organic' color schemes (you can do curves, etc..) with some great results.

just remeber your 'layering' order. remeber to build/layer from the tail forward. that way, you don't have any seams facing forward, that will 'pull' as air passes over them.

A small dispisable paintbrush is handy. Like really small! paint a fine line of trim solvent on the seam. you can also use clear nail polish.

I've also laid covering over covering with mixed results. On solid surfaces, just iron it on. Over open bays, it does get tricky, especially over a wing, like the points on a 'starburst' pattern on a wing. You need to be able to shrink it in place.

here's what some do in this case..
1. cover the wing as normal (base color)
2. cut out the 'decoration' pieces. lay the piece on the wing, and position it.
3. trace the location of teh 'decoaration' piece with a marker.
4. perforate the area with a pin like mad.
This allows teh gasses to escape while ironing, and aloows the covering under the stretch a little faster.

And on a last thought, there is a difference between the coveirings on the market. i find one 'Popular {monokote}' gasses more than the others. Experiment with the dirfferent brands, they all have their own feel and workability.

But just remeber, as with justabout everything in life..
patience and practice.
