I have some bedroom pine furniture which I wish to paint. Which paint is best to use?

Benjamin Moore sells an interior trim paint, AquaVelvet, that should be great. 3200 colors and 5 levels of finish, I'd go with Pearl. Another issue is prep work. You need to remove all dirt and oils and lightly sand with 180 paper. Use a tack cloth and a vac. Prime with their water based primer. After drying, resand with 200 paper and revac. Use a good brush and remember to remove all hardware. Allow to dry for 2-3 days before reinstalling hardware and using.
