I have used a little monokote but my mentor who passed away years ago hated it. He said it took a lot of heat to make it stick andthat he almost burned up his iron trying to cover his airplane with it.I really liked solar film but its not available in the U.S. and I did a search recently and found a company on line that sells it under a different name but they had a very limited supply. The metallic red was my favorite color at the time I built my Traine air 20.
