May I suggest the waxproducts from Autoglym. Very hard and makes the car very easy to Wash With car shampoo afterwards. I wax the car 1-2 times a year.
Im also living very Close to the Ocean and have never experienced any negative effects of that in the past. If you have a lot of dust winding up it can be smart to put those thin cover films on the "doorstep" of the car, and on top of the back bumper. Then you want scratch the car when Your foot slides over it on the way in or when you put stuff in the trunk. Works perfectly
