I mix/sell a lot of RL paint at the Hardware store where I’ve worked for a few years. If they’re painting with ANY bright/deep red/burgundy, we don’t let them out the door without a grey primer too!! We use a medium-grey primer, and insist they put on 2 coats MINIMUM…sometimes 3 of any red.
Also…use TOP-quality rollers & brushes.
Some “painters'” know these facts, some don’t!!
Thanks,
Faron
