Re: fiberglass fitment
Yep that's the way to do it. Cover everywhere you like the way it looks and don't want stuck with foil and packing tape. Then make you frame. Stretch out the fleece your using over your frame and over the weahterstripping lip. THen caram the weatherstripping back down on top of it. Then soak the fleece really well.
It depends on what I'm building and where it's going as too how I mount it. I try to use factory mounting locations wherever I can . But sometimes you can't. Light weight trim panels I will attach sometimes with grill cover ball and sockets. Heavier boxes and panels I try t use bolts or screws in strategic locations.
