Use a little lacquer thinner and some 4-0 steel wool. DO NOT USE ACETONE!!!. Acetone will take off the paint quicker, but will also damage the factory finish. Pour a little lacquer thinner in a glass bowl and use a small pad of 4-0 steel wool (NOT 3-0 WOOL!) Dip the wool in a tiny bit of thinner and begin to gently scrub. Keep watch for the finish coming up and lay off that area. Lacquer thinner will eat Rustoleum, but should not touch the finish. At most. You might have to use some polish on the finish when you are done stripping. No big deal.
