I don't know if some contamination ate the paint or what, I have a BSM color car.

Any advice? I think I will do a full wash tomorrow but i'm worried that after the wash that mark will still be there (as it looks like it would). How can I get it off? I did some searches and many people said a quick detailer and MF towel wipe or Scratch X, or Optimum No Rinse. I was wondering if i do that should I do it after my car is totally washed and dry? Or am I QDing the spot before my wash or during my wash? I don't want to use a quick detailer and start wiping around on a already dirty surrounding and making any swirls so I want to know do I wash the whole car before doing that.
Thank you for the inquiry I'd be happy to help. Wash the area first to remove the larger build ups. The problem with bird droppings is that they are often acidic and they can etch in to the clear coat within minutes. To remove the etchings there are only two options that I know of. The Chemical Guys Water Spot Remover can be used to remove light etchings that are hard to see or feel. The more traditional option is to polish that area, starting from a less aggressive polish moving up to a stronger one as needed. I would suggest starting with medium pressure and a polish like the Meguiar's M205 and move up to the M105 if need be. If that doesn't work you may need the extra power of a buffer to help work those polishes in. With the the help of a buffer you can remove the vast majority of surface imperfections from bird droppings. If you have any other questions please don't hesitate to ask.
