Well, I'm not going to inherit a balsa plantation, but I'm certainly not complaining.

The inks are not polyurethane. I'm not sure what they are actually. They are inks for vinyl, but I don't know what they are composed of. I don't even know what they use for thinner. It's all shrouded in a veil of secrecy.

But you're right about the test swatch. I plan to iron a piece of covering to a scrap of wood and see what happens. I airbrushed a little of the ink on my rotor blade tips to track them and it's held up fine so far without the clear over-coat.

What I didn't mention is that we also have several guns set up for "special effects." For example, we have guns to spray wisps, cob-webs and spatters in most of the colors we normally use.

Other than compatibility, I also have to be careful not to go overboard and try it all out on one airplane. I'm a good builder, but horrible at coming up with paint schemes. I could easily create a really colorful, yet hideously tacky art-plane.
