I'm painting a steering column with PPG Shop-Line JAU direct gloss acrylic urethane. The supplier sold me a matting agent to dull the gloss and a hardener (JH6670). I was told that this was all I needed.
I pulled up the technical data sheet online before mixing and I see that the mixing ratio includes a reducer. Do I need a reducer? Thanks.
