Solartex covering
 

How much covering is needed to cover a SIG 1/5 scale J-3 Cub?

One color most likely 2+ rolls Two colors = 4 or 3 with paint....
What I try to do is lay out the model outline \ area on the covering and get the most efficient use out of it.

Just remember that this has a grain and will shrink more in one direction than the other. This is important when you are laying out a pattern to get the most coverage out of a roll. I think you will be very pleased with this covering, easy to use and very durable.
