I don't even want to tell you how many ARF's I've bought both with Monokote and Ultracote that had wrinkles....lots of wrinkles and a lot of them I just couldn't get out. I've been building for 30+ years and done a lot of covering and when I slip into the ARF situation I have to look at the covering job and what I can do with it and say good enough is perfect. You want a perfect covering job? Build the thing yourself.......ya ain't gonna get a perfect covering job on an ARF, you'll get one that is satisfactory but that is it.
