i have a 2000 red z71 silverado. my problem is i work at a chemical plant where we produce acid and acidic products. sometimes this acid gets in the air and will get on our vehicles. we know it does because it smears on our windshields and sometimes our cars are covered in white powder. when i see this i wash my truck as soon as i get off work and then within a couple of days try to re-wax.what is the best way to protect my trucks paint. washing that much might be overkill but i m not taking any chances after what happened to my other truck.
