Hi

I have an interesting table that is the perfect size and shape for the end of my couch.

It has black metal legs and the top seems to be some sort of stone slab.

If I had to guess, I'd say it was slate, an inch thick, plain gray, nice beveled edge.

At some point it appears to have been painted matte black, but now the paint is a speckled mass of scratches. There is no peeling, though. The missing paint blotches look messy, beyond a simple 'distressed' look.

Repainting this is probably the best option, but how do you paint stone?
