I'm painting my room and I've already finished my base coat. It's a semi-gloss, purple color called Purple Suede. I want to make it a little bit darker so I was thinking about doing a faux antiqued leather texture that I saw at Home Depot. I think it'll look really good in my room. I was thinking about the top color being a really dark purple, almost black. Anyways, I read something about having to add a glaze to the 2nd paint before putting it on. Is that really necessary if I just get the 2nd paint in high-gloss? Also, from what I understand, I simply roll the 2nd paint on, then go over it with a fitch edge tool immediately? Should the 2nd paint go on just as thick as the base coat?
