Hi!
Been around 46 years in this hobby and tried nearly all coverings film available.
Silk and dope is fine but demands more of the user.
Monokote is good and very shiny, but I prefer Oracover as it shrinks much better and is much sturdier as it does not break (rip holes in open structures) as easy as Monokote. Oracover and Ultrakote are the same, made in Germany.
Solartex and Oratex are nearly the same but I prefer Oratex as it shrinks a bit better than Solartec and stays hard.These are suitable for larger planes like a CUB. For smaller planes in the .20-.40 class Ultrakote is the covering I prefer.
All the planes below has been covered with Oracover.
