I painted areas in a hallway that receives no direct sunlight with Chantilly Lace (Benjamin Moore's brightest white) around 18 months ago. It has not yellowed yet. It is directly adjacent to some trim that was painted with white acrylic, so I have a bit of a reference. I cannot say what it will look like in 10 years, but so far so good. It looks and feels way better than the acrylic too.Have you noticed any yellowing with BM Advance?
