I am finishing up my GP extra 300. How do i cover the belly pan. I am using film and I cant for the life of me figure it out. Do I cover the edges of the pan then do the center of the wing inside the pan. Do I cover up to the edge of the pan then cover the interior of the pan with one sheet so you don't see the middle of the wing. I am confused please shed some light on this. I couldn't find any answers in the forum search.
