Yes and No on the fiberglass bit. I have developed extremely secretive ways of making fiberglass parts :-)
If you look back at the photos where you can still see the cereal boxes, those are HUGE when getting the fiberglass to separate. Yes, Fiberglass will come off of standard kitchen aluminum foil. Yes, fiberglass will come off from the aluminum tape, but when combined with a strong backing, its almost a once shot process. The hard part is planning. You need to use some strategery, plan to cover large area with the backing, but leave enough overlap of AL tape or AL foil so you can still remove the piece from the car. I had a hard time getting it off the front bumper of the subaru because I neglected the top portion for the license plate holes. That was 100% aluminum tape, which did not want to leave go from the bumper. I had to separate fiberglass from tape while it was on the car. A process that is best described more profanity having an orgy with other profanities. :-)
So yes it will work, but you need to plan ahead. Know where you'll need to separate from the piece. Overlap 20% more than you think you'll need. I'm getting better with my work, but its better to go 3 to 4 inches past where you'll fiberglass. If you have NEVER fiberglass before, you need to start on test pieces. Getting sloppy with fiberglass will permanently leaves globs on your bumper!
If you're interested, or want more info ask. I can give you alot of pointers on where to start!
