I posted a topic about buying what I thought was an air comp. but it was a air tank not a comp. . Anyways I dont have the money to buy one know and was wondering for those of you who drive the car around the block to get the water out, do you guys do it before drying or after drying? The other day I did it before and after and I still had water in the mirrors and moldings, I have a MB and it has a ton of places where water gets trapped and I dont like using those cans of comp. air. Guess I just need to save up and get a air comp.
