How often should I wash my car?

[Buckethead]

I tell you these goddamn birds are on a rampage!!!


Hand washed the car myself yesterday, and waxed it using the new turtle wax clear ice, (which rules). Little fuckers shit on it this morning...
Once a week, twice a week? What about waxing, how much is too much? I don't wanna wear out the new paint job... Another friend of mine said that I was overthinking the paint job. He said new paint should last 7 years.. That true?
I almost punched him in the face for that.



Thanks!
