We're currently doing a small kitchen reno and I was thinking it might be a good time to refinish our old porcelain enamel sink. It's ine of those old farmhouse type sinks with a double drain board and single bowl - we bought it over 30 years ago at a junk shop and I do really love it. But the surface is chipped and the bowl is no longer shiny. The place I spoke with will do a baked-on powder coat finish. I'd love to hear if anyone has had experience with this type of refinishing. Is it durable enough for a kitchen sink? This isn't the painted-on enamel which I know is sometimes worse than what you stared out with. Comments?
