I think you are probably tired of your kitchen countertop. That takes a lot of wear and tear so don't try to get it done on the cheap! Go to a home hardware and ask for the same paint that is made to paint bathtubs. It's deadly on your lungs if you don't have a lot of fresh air circulating in your room. The trick is to have it prepped properly. No oil, grease or caulking! Lots of tsp and elbow grease! Schedule to do it in warm weather so you can open all the windows. Invest in a proper mask.
You must dand the formica in order for the paint to adhere.
