Paint not setting up.

Product description says you needed to add 100 % BS *** to the base coat before the 1 to 1 hardener. https://www.paintdocs.com/docs/webPDF.jsp?SITEID=SWPCGAUTO&doctype=PDS&prodno=764423132600&lang=2

I'm not using a "base coat system," it is a single stage top coat. No clear coat involved. Am I missing something here? I wanted the dash board to be durable...didn't want to do a "rattle can" job or shoot some straight acrylic and I didn't want to screw around with clear coat on a dash board. Relating that to the dealer, they said this was just the thing I needed. Ultra 7000 single stage top coat. It was the first time I stopped at the Sherwin Williams dealer. We have been spraying DuPont Emron and NASON Ful-Thane single stage we get from Crowe Burlingame and have never had a problem with it at our shop.
