I have a black '05 Tacoma and I work at a construction company where there's a lot of painting that goes on daily. I really need to either get a car cover, or clay my truck every month because the overspray gets pretty bad at times. I read the stickies and plan on doing a better detail than I usually do. but my questions is... Working at a place where 90% of the ground is limestone and dirt and when the wind blows its like a huge dust cloud in the area, would it be a good idea to get a car cover for protection from the overspray or would it do some harm to the paint from the wind possibly blowing limestone dust/dirt in between the truck and the cover?
