You will usually cover the entire plane with your base color and then apply your trim colors on top. Doing a job like you have found is time consuming if you want a good looking plane, but they are well worth the effort. A lot of the ARFs use a stick on kind of covering which would make it easier to apply. I prefer the Windex method for my trim pieces which once applied takes about 24 hours to cure. RCU moderator Minnflyer has a video that you can watch that will give you most all the basics and a good start on covering. Good Luck, Dave
