Help! We have very nice formica counters in our home, but the previous owner put in "black" counters, they look like slate. Although very attractive, the dark color just isn't what I would like to have. Not having a big budget to have them replaced, I was wondering if there is a paint available, that I could change the color of the counters, but that would also be durable and not scratch easily. Any advice you could give would be very much appreciated.
