this covering thing is driving me crazy! I built a 1\5 waco WMF3 a few years ago and used a iron on covering that was pre painted canvas and simply can't remember what it was. XXXpensive but worth it for the ease and quickness of application, never used dope and do not know how to affix it prior to dopeing it. I paint very well and would like to paint it myself but just not sure what to do now.
