I was painting house trim with an oil base paint (Frazee). Paint has a habit of dripping in places you don't want it to go. Including the cloths on your body. Well... the paint dripped on the back of me and unfortunately I sat on my leather car seat. You can probably read between the lines and hear my wife yelling at the same time! I've tried paint thinner with a mild abrasive cloth. Doesn't work! Is there any other way of removing this paint from leather?
