I was recently using my heat gun to tighten the Ultracoat on my plane. I'm not sure if I applied to much heat, or the seam was bad, either way, the seam opened at the fuselage. Its about a 1/8th inch wide at its peak, and about 1 inch long. Should I just cut a small strip and patch over this section, or remove the existing peice, and redo the whole section.
I've not applied Ultracoat before, so I wouldn't know if a 2"x2" patch will show alot or not.

I know this is kind of after the fact but whenever you need to reshrink the covering to get wrinkles out, you should always iron the seams first to make sure they are totally secure then apply your heat gun heat carefully just enough to get out the wrinkles.
Now, I would use my iron and try to get as much of the wrinkles as you can out of the pulled away seam and cut a patch about 1/4" to 3/8" larger than the opening. Round off the corners of the patch before ironing it down. Just iron the patch carefully to the exhisting covering. It will show a bit but its better than leaving it open. Now that the patch is secured, take your iron and go over the seams again and lightly brush the iron over the covering to pull it slightly taught. Dont shrink it too much or you'll get the same problem.
