You can't fight the EPA. Alkyd paints are going the way of the dinosaur because the mineral spirits used to thin them cause low level ozone pollution in the air. All the research money is going into developing water based coatings that can match the durability and hardness of oil based paints.

If you have a General Paint, Kwal Paint, Frazee Paint, Colorwheel Paint or Parker Paint store in your area, ask anyone at the sales counter to shake up a quart of Monamel satin for you. Use a Q-tip to paint some of that Monamel onto a paint mixing stick and see how it spreads and what it looks like when it's dry.

Monamel is a water wash-up paint, but it forms a film that's nearly as hard and durable as an alkyd paint and that's what you need on door frames near light switches where dirt always collects.

At least it'll be a start in finding a paint to replace the BM satin Impervo you've been using.

Envirogard is another water washable paint that's worth looking at. Different chemistry, but it still forms a film that's much more durable than conventional latex paints.
