Matt,

That certainly is a wealth of information!

I have the .3-ounce veil. I didn't do enough research to learn that the light veil is used for stiffness, not strength or ding resistance. It also sounds as though I should get nitrate dope to apply the veil before filling it with the urethane. Or possibly hitting it with a high-bulk sandable primer as filler and finishing with the urethane.

Your other idea, to use it *under* the skin for stiffness, is a real possibility. (Although it sounds as though I'd need to let the nitrate or epoxy cure with the sheeting tacked and formed to plastic wrap-covered ribs.) That would impart the stiffness with, I would hope, little added weight, and then use glass on the top surface.

I had planned to use carbon rods glued into the rib alignment holes until I weighed the 5/16 rod. It came to 3.2 ounces and there would be two for each wing panel, or real close to a pound of weight.

Or I may be seriously over-engineering this build.

Again, many thanks for your time and detailed information.

Cheers,
Richard
