: A long time ago I built a plywood sail boat and covered the outside with
: Sears polyester and glass. What was so different about this was, the first
: coat was designed to dry tacky like tape. Then when you placed the glass
: on your boat it held in place and you didn't have a wrinkle problem and no
: slippage. Then when you put on the next regular polyester it finished
: setting up the first special coat. I thought it was great and I don't
: understand why you don't see it for sale anymore.

The tacky polyester just did not contain the wax. You can buy polyester from professional suppliers that does not have the wax. You can also buy the wax additive. Gelcoat is just polyester resin without the wax (plus some pigment) so it gels instead of hardens.
