I just bought it two days ago. The directions told me to air it for 2 days.. so I did. Then I used it today on my car. (I just got it so it still has the dealer wax) It left some kind of residue on it. (Anyone know what it was?) I had to use water and a nice cloth to get it off. Also, what is the best way to make the car look clean... (its black) Dust gets on it and it looks really dirty. (are those machine car washes okay to use?) I don't really know how to wax a car, and I also usually don't wash my cars except for this one *first one, only 16*... so I was wondering, what should I do to make it clean on a daily basis. or every 2 weeks basis. Please help me out, I really appreciate it.
