I'll add details about which interior paint products we use and why as I add more information to the new web site. For now, suffice to say that we prefer to use Benjamin Moore's Aura Interior paint as much as possible (which is most of the time). If we need to save money on paint (like on rentals or apartments), we use Benjamin Moore's Ultra Spec 500, which is a durable cheaper paint. We also use Ultra Spec on lighter colored walls, even in fancy, nice houses, since it can perform about as well as Aura and costs half as much. For trim and doors, we always use Benjamin Moore's Aura or Advance (their high tech oil-based paint that cleans up with soap and water), or we use one of Benjamin Moore's Industrial paint products, depending on the durability required for the surface we're painting.
