I would like some advice on whether to use 631 or 651 (matte white) for an indoor wall (painted at least 120 days ago). The job is big, and it will be all matte vinyl. I was wondering how well the 631 will hold up. I've used it in the past, and seen it peel up. I could have had a bad roll. Does any have experience with both, and can help? Thank you.
