I have a pair of 90 year old matching doors. I didn't strip, only sanded good. I didn't use primer, the door has never had red or pink paint on it. After 2 full coats of white enamel paint, the pink was still there. Sherwin Williams guy had never seen anything like it before. He suggested the cover stain primer, I sanded some of the door and it looks like with 3 coats of the primer the pink will be covered.
I'm just wondering if any of you have ever seen this before.
