This question comes through the blog by Kathy:

HELP!!!

I have started to work with Resin, when I take my item out of the mold the side that has been exposed to the air is sticky.  Do you have any ideas what I could be doing wrong?  We are adding about about 3 drops of hardener per ounce.

Kathy,It sounds like you are using polyester resin?  If so, it commonly occurs that the surface exposed to air will remain tacky.  You can either sand that surface off to get to cured resin, or seal the resin with an acrylic spray.  Our Resin spray works well for this:
