I will soon be building a fiberglass subwoofer enclosure for my RT doing the usual fiberglass mold of one of the rear corners in the trunk. Over the years I’ve built many of these and the car always smells of that nasty resin odor for days. This time I’m thinking of doing the mold outside of the vehicle by pulling out the trunk interior panel, and making the mold outside of the car. No mess, no smell in the car etc. Has anyone here ever tried it this way? Looks like the interior panel will hold their shape outside of the vehicle.
