The other day I posted a thread about bird bombs. My 1 month old BMW 330i had been raided by birds and within 4 hours, my paint had been etched in 4 places. Needless to say, I was heartbroken. I posted a thread asking for advice and ShowroomLincoln suggested 3M Swirlmark remover. I stopped by the local NAPA auto store as I knew they carried 3M products, washed my car, used the Swirlmark remover and followed up with a little 3M Imperial Hand Glaze and a coat of Blitz. To my amazement the spots were gone! Thank you very much for your help! I hope I can return the favor some day.
