Waterspots on M3

[paulvinh]

During the hottest weekend of Southern California with temperatures hitting 120f, my black m3 was unfortunate enough to get rained on and baked in the sun. Now my hood is left with water spots that I can not remove. Can someone help tell me what I can do?

Wax?

Take it to a detailer, or buy some quality polish and do it yourself.

Try some white vinegar on a good microfiber cloth. A little rubbing should take care of them.

This is one of the reasons I narrowed my color choices to metallic silver and white. I visited the Tesla store the morning after a rain..the black, dark blue, dark gray (MSM), and red M3s all showed water spots to varying degrees while the metallic silver and white did not.

I am having this issue after washing my car with my glass roof. Might try some rubbing alcohol on the glass to see if that clears it up.
As far as your paint, you could also clay bar it (not the easiest thing to do). Once you get them off, I suggest a good polish and wax to protect from it. Make sure you rewax soon enough so you don't have to go through the spot removal process again.

The problem with these colors where I live is bee poop, yes that is right. I have a white car that I now park outside and by three days outside it is absolutely covered with yellow spots all over the place. I looked it up because I was wondering what the hell is dropping yellow stains all over my car.

When washing my car I use a squeegee to get rid of the water on the roof and windows, then go back and wipe with a clean towel.

Second a 50/50 vinegar/water mix a microfiber clothe. But if you want to prevent in future, go get it detailed and then ceramic coated.

Metallic silver is the way to go if you want your car looking clean. Even after a 400 miles road trip it still looked clean.

I also have a black M3 and saw this on YouTube a while back. Thought I'd pass it along.

Check out this video. It shows a few of the popular methods:

TLDR: Diluted wheel acid took it right off.

This was the stuff he was using in the vid:
Wheel Acid | Car Brite

Not sure where to get the stuff, but good luck.

Maguiars waterless wax works for me.
