Today I was washing and waxing and I noticed some paint streaks

Is there a chance that it came like that from Nissan, or was it definitely the previous owner?

 

It would probably be helpful if you posted some pictures of the "streaks".

 

well, they are really really faint, I'm not sure a camera would be able to show it... I'll try to get some pics when I have time

...but I'm pretty sure most people know what paint streaks look like...

 

Most likely previous owner.

 

yea, I thought so. I was hoping it wasn't >
I also found 2 paint drops. One on the rear strut bar (htf did it get there) and one on the rear right fender. wowwwwww
And wow the right door progressively gets unshiny as u look from rear -> front. Looks like they forgot clear coat or was going for the half matte black look! My bumper is slightly matte also!
When I got the car I didn't know paint was that expensive... ohnoes. I fail.

 

sounds like the previous owner had some incidents and tried to get them covered up the best they could.

 

Try a hair dryer on the streaks, Get it warm right on the streak and see if it magically dissapears.

The delivery protection film sometimes leaves marks in the clear coat. heating them up makes them go away.
