I ran across this thread and had to ad that I loved world model planes but since they started using toughlon, I wont buy anymore. Also the aerokote that sig uses is nothing more than saran wrap ( I am sure that somewhere it says glad on the covering) Anyway its a shame becasue the wm chippie is my favorite plane. Now when I look at the ad if it says anything like china kote or aero kote or toughlon I just move on. I know some day they all will be china kote, unless we stop buying thier crap. But I am getting better at covering ..
