Hi guys, this is my first hand experience with painting fiberglass;
I work for Epic Doors which manufactures high-performance fiberglass entry doors. We evaluated several paint suppliers including TruCoat 623, Sherwin Williams Polane 2K Acrylic, and Aquasurtech D200.
We were looking for an environmentally friendly, single component water based paint that was super durable, had great adhesion and laid down smooth.
Based upon our evaluation we selected TruCoat 623. It was much more environmentally friendly than Polane 2K and is a single component and
TruCoat had better adhesion than D200 and was priced better.
