Does anyone use polyester resin? I always had success using the K&B line of Polyester resin products, but they are no longer around (neither are 3 of my LHS), so I wanted to see whats the most popular glassing resins and primers are in favor nowadays. Thanks.

Zpoxy is better plus it's almost odorless. Takes longer to cure and you won't get complaints from the peanut gallery.
Just stick to the ratios on the mix more hardener doesn't make it cure faster.
Primer I get the high build stuff from pep boys duplicolor or similar.
