RE: Polyester Resin - Where to buy
I have found that Napa Brand Polyester Resin to work better than most brands. It is availanle at any Napa.
I thin it with MEK to insure a good bond.
It wicks into the glass easier than other brands.
It is the only brand I use anymore. I use it for full scale glass repairs too!
It is a little more expensive than Bondo brand.
However, Epoxy will cure over polyester. Polyester applied over epoxy will not cure.
When strength is my primary concern, I only use West System Epoxies.
