First of all, I love this board. I am new here and am very relieved that I am not the only fanatic when it comes to detailing my car. The other day, from the time I got to the office and when I went out for lunch I had four bird bombs on the roof of my car. I got out my quick detail spray and 100% USA cotton towel to wash it off and it left a stain/imprint on the paint. After work I got out the 3M Imperial Hand Glaze and this helped a little, but I can still see the marks. Questions: 1) what can you do to prevent these marks? 2) how can you get rid of them, once they happen? Thanks for you help.
