I really don't understand the aversion to Monokote I here about on RCU. Here is the Sig Somethin Extra I'm covering showing the turtledeck. It wasn't hard. I just cut a paper cutout so I knew the shape of the Monokote to cut. Made sure it laid flat. Tacked the corners and used a heat until the covering started to show signs of shrinking, then I used a fuzzy glove to press against the covering. Presto no wrinkles. I've still got the top five colors on the wing to windex on. Everything so far has not used the windex method.
