Art,
For attachments, the file size must not exceed 102400 bytes... or 102kb. There are some little 'cling-ons' that add to the file side as sent, so I've found that 100-102kb photo attachments bounce. I've had to get them down to 96-98kb maximum before they upload.

Did you use purpose-made mold release wax, or just car wax? Mold release wax makes a difference. Polyester resin contains solvents that can attack regular wax. For that reason, when I'm playing with molds, I prefer to use epoxy resin.

In addition, consider spraying the plug or mold with PVA (poly vinyl alcohol) and letting it dry before laying-up the fiberglass. When you're done, any PVA residue rinses off easily.

For small parts, I usually spray it with a PreVal. It's a glass jar with 'aerosol' spray nozzel that accepts a screw-on, disposable pressure cannister. Pour whatever you want to spray into the glass jar, attach a pressure cannister, and spray away.
