Ok this is a very odd question i know but let me tell you what is happening. I noticed a few weeks ago after i washed my truck i came out the next morning and there were odd black little spots on my hood and roof. When i removed them with QD it appeared that they had etched my paint as you could see a perfect spot where they had been sitting. Well my first thought was tree sap so i moved to a different spot in my yard the next night and they disappeared for a couple of days but there they were again. Now i am not happy. But i did notice many bugs dead on my hood each morning. So my question is this could bug poop be causing this problem and if so has anyone experienced this and how in the world do i stop it??
