I have been trying to get R-M 66B84, Dark Fawn in a single stage for the interior. I had a 1/2 pint of PPG Omni mixed and gave it to a guy last spring to paint with, but I don't think he didn't used any flattener and it all appears to be too much gloss. I can see sand scratches thru the paint too, so it all needs to come back off. I have sent messages to R-M twice with no response about where to buy their paint. I have heard it is a better quality than the Omni.
