I can report on a 21st Century painted theme.....DON'T DO IT.

Unless you're using unpainted and painting it with Latex. They discontinued most of the colors, don't take a chance and box yourself in with 21st Century. I ended up having to match with mixed Latex from Home Depot.

21st Cent. fabric is heavy and my 1/5 Waco ended up with a 15 pound AUW and 1 - 1/2 pounds is just ballast. It flies fine, but why go that route when you don't have to? I'd have preferred it was 14 or even 13 pounds. If it wasn't so pretty all done, or if it didn't fly very well, I'd peel it off and redo everything. But it is pretty and it does fly well.
