Hi Tim -

Answers to your questions ...

POLYURETHANE ACRYLIC ENAMEL
The spec sheet for Delstar that you mentioned describes it as "Delstar/Delthane Polyurethane Acrylic Enamel"
http://www.tcpglobal.com/docs/ppgdarp.pdf

HARDENER
I was wrong about hardeners with 2K urethane paint. I thought that hardeners and catylists were the same. I use reducer and a catylist with the "nason Ful-Thane 2K Urethane" paints that I have used for small jobs. The hardener that I have is for epoxy primer.

FLATTENING AGENTS
Why did the mgr of the paint supply store say that he cannot successfully flatten paint? What's the secrete?

SAME SYSTEM
What should I spray over the gray epoxy primer to show me the high and low spots when wet sanding before shooting the black top coat?

Thanks again to everyone for my education. "I didn't know how much I didn't know!"
