My husband and I have painted every kind of appliance except a stove, and with amazingly good results. When we’ve had rust spots, we’ve sanded them down until smooth to the touch, then painted with some anti-rust paint like you use to prime outdoor furniture (available in spray cans at the home improvement stores). Be sure to use spray appliance paint, also available at the home improvement places. The main thing is to not get in a hurry. Make even strokes with the paint, and don’t get too close–it’ll be drippy if you do. It’s better to do lots of coats than one heavy one. BIG TIP: Make sure the appliance is clean and dustfree, and that you apply it away from the wind. The only less-than-successful effort was done in the wind, and we didn’t get a smooth coat. Hope it goes well!
