I just covered my Sig. The hardest part was the wing. I had a veteran come over and help me with that part. The middle section where the wing is sheeted was the hardest part of the wing. I found that if you put a 4" piece across the middle first, both top and bottom. I then covered the wing panels applying over the middle section. If you press over that section with a damp cold sponge first them heat the monocoat and quickly cool that section down with the sponge again the glue sets faster and doesn't bubble as much. If you get bubbles take a small pin and let the air out.

I checked my irons heat with my wife meat thermometer. I turned it up until it read 275 degrees and made a note of the setting.
