I want to paint some older "antique" furniture using a technique I saw in Martha Stewart Mag. from 2 years ago. Using black paint, rather than the usual white to redo furniture, the items redone in the mag looked great-. Although to get an ebonized look, oil based paint was used with paint thinner and linseed. Is there an interior oil paint or just exterior adn what would be the best sheen, glossy or mat. The black paint chips I picked up looked weird- either too gray or to "purple". I would like a very dark brownish grey, but am not sure what brand, type etc,. to use as nothing was listed. I thought if anyone was a paint expert or has painted furniture before, may have some advice.
