I've been looking into painting the 4" x 2' areas of my epoxy over polyester fiberglass repair. 2-part polyurethanes are $50/qt and would not be color matched, i.e. I'd buy white and have to darken it myself, somehow. Dropped by an autopaint store, $35 for a pint or quart for acrylic enamel.
Then I ran across this website:
www.epoxyproducts.com It has a huge amount of information about epoxy and polyurethanes. So I thought I'd share it. Still haven't found how to color match with a polyurethane, though. Would an epoxy pigment work?
Cheers,
