I went paint shopping saturday and I went to Napa's NY main store and gave the paint guy 2 color swatches of vinyl interior and told him to match them in a acrylic enamel, then he hands me the paint book and tells me he cannot match them with his paint matching gun as there too small, I look through the book and find nothing. I went to a PPG dealer A Saves autobody supplies in Syracuse and handed them the swatches and said there computers were down for the day ( closed the paint dept, guys were cleaning up ) but that they could match it up with there camera if I left the swatches with them. I did leave them, and name and phone # and how much of each I needed, and he asked me what I wanted it mixed in, and I told him acrylic enamel single stage, and he said Ok, my question is will my Martin Senour Acrylic Enamel primer be ok for use with the PPG Acrylic Enamel? The guys at the store said yes it would be, just want to make shure b4 I get the paint mixed.
