Mr. Paint is probably right, actually, I painted my kitchen Benj. Moore deep rose, and it took about 5 coats to paint walls that had had flat white paint on them. It was brutal, but now looks great.
I've used RL satin paint in a baby's room, and I must say I wasn't totally thrilled - it sure doesn't go very far. But, now that it's on, it's great. The finish is even, and the colors are fabulous!! I'm also using the suede in the master bedroom, and although I'm struggling a little to get the technique exactly the way I want it, I'm happy so far.
