I'm looking to purchase a BMW '03 BMW 530i that was previously a garaged car. It will now be a daily driver that will be parked outside in the driveway at home. I'd say the paint is currently an 8 out of 10 (black), so my major concern is protection of the paint. I live in VA, and the car will be in direct sunlight in the heat of the summer, and in the winter elements (rain, sleet etc.) in the winter. What's a good wax for long term "protection" from the elements? I would like a nice shine, but that's secondary to the need for paint protection. Anyone use a synthetic/polymer wax or some type of specialty wax not found on the store shelves, or online?
