i washed my car today, nice and shinny, found 3 hairline scratch on my driver side small door, this is in San Francisco, the only day i park my car out on the street is monday night in Sunset near the beach. lucky the scratch ain't so deep i can wax it out. i strongly recommand you DON'T park you car out side! especially in san francisco!

 

It is possible that the scratches came FROM the wash.

 

does it look like someone keyed your car, or was it because of something in the san fransisco environment that caused that?

 

yup someone keyed my door

 

Either the keys were made of rubber or the guy who keyed it was extremely weak. I've never seen someone being able to wax out scratches from being keyed

 

yea you're right
it's a weak key scratches
somehow you can still see it under sunlight when you look extremely close
like i've said i still have a bit of luck
because it'll cost an arm and leg for the paint job....

 

I believe thats called "swirl marks."
the best way to avoid those would be to use good washing meet (sheep wool) and good drying towel (microfiber, chamois, or something along those lines.)
And make sure they are ALWAYS clean before use.
