Re: gum preservatves (polyester resin)

Living in NC, home of the long-leaf pine, I'll have to disagree. Maybe there is a "man-made" resin out there, but there certainly is a pine resin that comes from the bark and needles of pine trees. Rosin is extracted from that, as far as I know.

Sorry it's resin not rosin. Two very different substances. Resin is man
