Default Fiberglass Questions

I want to make some simple speaker enclosures/backs out of fiberglass. I believe I know the basics but I have some questions:
1. Is there something simple to use as a release agent (ie: wax, tape, tin foil, shave cream , etc...)??
2. How many layers will be enough?? Non-structural items.
3. Which resin would be best??

Thanks for any help.

Saran Wrap works pretty good

Packing tape works well, but will leave the image of the tape.

You can make a mold from some foam, like styrofoam from home depot for insulation. Test it for compatability with your resin first.

When I do a fiberglass part the mold is very slick and several coats of mold release wax works fine,
I don't know what you are using for your buck/mold but if it is rather grainy and porous I like to use aluminum foil,
I would still run two layers of mat and be sure to roll out excess resin, you really want just enough resin to wet the mat fully,
