ok there is a small chance i could be driving accross the country tomorrow from ny to las vegas. i dont plan on anything happening, but i was wondering if iw ould need some type of bra or something for my car to protect it from dust and rocks while driving accross the country. if so where can i get on cheap, im REALLY tight on money. or maybe i could borrow one from someone. also, i would have to change my oil when i get there which shouldnt be to hard i have mazda factory filters and i could bring oil.
