Back in August, I painted my bedroom. It took me some time to get around to painting the trim. When it's your bedroom, moving everything around does get old fast. I got a little blue paint on the window and on the trim back in August. But it was a good way to test to see how well the paint covered.
I used Olympic High-Gloss Interior/Exterior latex paint. Even though it doesn't call itself ONE, it's part of the same series. I had good luck with Olympic One in the past, so I used this from the trim. Like the garage, I had it tinted to Frostine (AF-5) which is Benjamin Moore color. It looks pretty much like white but something that has a little pigment covers better than a pure ultra white.
Because of the photos and lack of much light, it really is hard to tell in the picture, but it covered pretty well. I also could tell they didn't even bother painting the trim when they put it up in the house before we moved in. Now it's all nice, shiny, and clean.
