Lord C'mon Guys..
Don't knock it until you try it first. There was ZERO grit or dirt on my car before or after. There is only so much you can do with a blower, the rest is done with towels.
Let us think this out first.
I am almost sure the single best way to kill a paint finish is to never wash your car period.
You can put swirl mark into the finish if you don't change wash rags and use the wrong soaps.
When I used the blower it was at a down angle from the top. I then moved my way around the car doing the windows. And finished with the hood and trunk. The bottom was done with towels to avoid kicking dirt. Not that this was a problem after having just used it to clean the yard and roof hours before.
For those willing to try, give me your feed back. For everone else, we heard your side already, get over it.
