When I made the mold of my hatch interior, I covered the area in masking tape, then put aluminum foil over that just to be safe from any spot I might not have sealed well. I did the fiberglass mold and just had to peel the tape off the carpet, then pick the tape and foil off of the glass. Most of it comes off fine but little pieces wouldnt come off well..

The tape is really there so that you can pull the mold away from the area you're covering in glass, since the resin will glue on to whatever you're molding.

Also note, hardened resin will not come off of anything, make sure you mask around the area to avoid damages from drips.
