Southern California here. I had some interior paint work done in January, all with Dunn Edwards Suprema. The result is very nice looking, but the paint does not stand up to even the slightest scrape. I find that I'm frequently touching up scratches in the paint. My folks' house still has paint from the 80s, and that old paint seems much more resilient. Were regulations enacted since the 80s that has resulted in less-durable paint?
