Two Krylon products came in handy for painting the tail feathers of the Jupiter Duck. Easy Tack allows you to make a painting mask, use it, the remove it easily. You don’t want to make a permanent bond. Then for painting I used another Krylon product called Short Cuts paint. Seemed to work well on Depron. I used white craft paper for the mask. And when drawing the mask I just moved the poster board templates around and traced it again.
