I am considering using a car cover on a regularly driven car that I park outside. The problem is my current house doesn't have the garage space for this car, and but I would like to protect it until I am able to move to a place with a bigger garage (this car is stored winters at another garage). My main concerns are protecting the paint from the sun, bird droppings, and tree debris. Is this a practical idea, or more trouble than it's worth? The covers I am looking at have Kimberly-Clark Block-it material. There are three levels available, 100, 200, 300. I am looking at the 200 now, since it is not too much more expensive than the 100, and it is almost half the price of the 300. Any advice and experiences would be appreciated. Previous to this, I have only used car covers on vehicles stored inside.
