Before covering my wing I did some research and watched several videos. Very informative but I may have missed something. Basicly the instructions say to seal the edges and then shrink the middle. Before shrinking the middle should the iron be run over the ribs to stick the Monocoat to it or just shrink the entire center? As a side note I have a non-contact thermometer that I used to check the temp of the iron. Temps came up fast in the middle but the toe and heel took a while to reach a usable temp. In other words I needed to let the iron set for a while before it was able to do the job across the face. </p>
Simply put, you want to tack the perimeter, then shrink the middle (preferably with a heat gun which gives you better control) without sticking the covering to the ribs. You want the covering to be able to move around as your shrinking it over the various ribs. There will be times, depending on the shape of your wing (like the wing tips of an Astro Hog), were you'll need to lift, stretch and restick the covering material to smooth it around compound curves. I've had some wings that have taken 2 to 3 hours to get the covering to stretch over compound curves around wingtips without wrinkles.
After everything has been shrunk you want to run your iron over the ribs and leading/trailing edges to make sure the covering has glued down and is not just floating over it. This is where the strength comes from.
