The title says it all, I live in sunny Florida and my car is outside 24/7. It sits in direct sunlight all day, and under a tree at night. Sees plenty of sap, bird droppings and LOTS OF RAIN AND SUN during the summer. It sees rain almost every afternoon. Right now I am using Meguiars Ultimate Liquid Wax once every 3 months on average. Water beads very well at first, but after a couple rain showers it doesnt bead as well, even after washing it. There is one spot on rear driverside door that looks to be getting hazy so I want to keep it waxed and protected best I can. I am not overly concerned about the wax providing a shine, I just want the best protection. What would be the best affordable, and easy to obtain option(s)?
