No one size fits all solution for me. I’m more use to Sherwin’s products after years of using them, especially, proclassic hybrid, super paint and duration, both interior and exterior. Promar 200 isn’t bad for, I think, less than 30 a gallon but I’ve been moving away from it since going back on my own again, I think Duration is going to be my go to for walls, especially since they’ve cut my price down. I also have a really good rep from Sherwin who will help me figure out what I need and what’s available now that paint availability is so spotty and he’s been pretty good at getting my business by pushing pricing down.
I do still use Hirshfields a bit though, I really like their fresh start enamel underbody, especially for painting previously stained cabinets and trim, they carry Wooster brushes, rollers and poles, Old Masters products like the Armor I usually use for poly, General Finishes Gel Stain and reinforced builders paper. They’ve also been a lot better at being able to get some kind of oil primer for me during this shortage. Their Regal and Aura are great wall paints when they work but I’ve had a few weird batches too.
