"I've Trusted Sherwin Williams A-100 Paint for 20 Years. As a Professional Painter it has Paid off for me using Sherwin Williams Products. A-100 covers well, where other store brands were a disapointment. I Find I don't have to worry much about its Durability, and longevity. My customers like that. It has proven to me, to be a reliable, and trusted product, that's been a good selling point for my Painting Business."
