It needs to cool for the adhesive to attach firmly. Fiberglass does not dissipate heat as quickly as wood, so be prepared to hold the film in place for 3 to 5 seconds. Here, the side of the pant is finished, and I am beginning to stretch the film around to the underside. The curve is quite sharp, and the bottom of the pant is nearly flat. In this situation, more heat needs to be applied, and more pull will be required to stretch the film around the curve.
Sharp curves take a little more time than nice, big, round ones.
Here, one side of the pant is nearly complete. The covering extends just past the centerline along the top and bottom of the pant. To cover the top of the pant, I used the small rounded shoe, using the same technique as I used on the side. Draw a centerline, end to end, on the top and bottom of the pant. Mark the center at the forward and aft ends of the pant.
