Good grief, now I need to fill the gap between the two halves of the intersection fairing for the wheel pants. Made a support to hold the epoxy/microballons and wrapped the forward fairing with shrink wrap to prevent the mixture from adhering. Attached to wheel pant halves together, then applied a liberal amount of the epoxy/microballons to the gap of the intersection fairing.
Once it sets up, the plan is to sand it down to the final shape and size, then cover the entire structure with a mixture of West 105/205 and Acetone, mixed 50/50.
