Now it is time to glue the fiberglass skin on to the rebuilt plywood on the front of the Class C rv.
After gluing and stapling the fiberglass, the front panel is cut out for the window. The original cutout on the fiberglass was used as the pattern. If necessary use masking tape to outline the cutout to prevent the fiberglass from being scuffed/scratched by the jigsaw. Have to give credit to the Bosch jigsaw. Cutting with it is a pleasure compared to old egg beaters Black & Decker used to put out (still do?)
Black butyl putty tape is used to seal the window to the fiberglass.
That stuff is tenacious, but it does clean up pretty easy with "Orange Goop" type automotive soap.
