    Puzzled by these stains...

    Hey MOL!

    I had a friend bring me her new car because there is severe staining on the back of it. She said these stains were originally dark brown in color, similar to coffee, and the only way she was able to lessen them was to pour hot water on them. All of these yellow dots were left on the paint afterwards though. Lastly, she said at her work, they have been painting the buildings, but I'm not sure what could have gotten on her paint to cause these stains. They all appear to have etched into the paint as well.

    I tried:
    -Extra fine clay
    -Fine clay
    -E1 Clay mitt
    -DG 501 by hand
    -SX 2.0 by hand
    -DUB Wheel Cleaner
    -Super Degreaser
    -Goo Gone/Mineral Spirits
    -M105 on a MF pad via GG BOSS 15


    Nothing had an effect on any of the staining. I'm curious what everyone's thoughts are? I've never encountered something like this before. Usually it's just some rust spots from rail dust or crazy tree sap.

    Thank you all for your time!

    I have received suggestions from a couple of our pro reps to try to wash with any acidic product safe for paint. They have suggested RTU white vinegar, or our Extreme Marine Water Spot Remover.

    I did not try WD40 yet. I will keep everyone updated though! I want to try and have a few ideas before I have her drive back over to my house.
