I just returned after 6 months of being underway. I left my car under a tree unfortunately. It was not driven nor washed during that time. I now have some type of dark red substance on the paint. It is not sticky and it feels almost embedded into the clear coat. It looks like a bug splatter but of course it wasn't driven and its on the roof and hood. I am not sure if there is a sap that looks like this or bird droppings. I tried washing it off but no luck. Claying with pinnacle ultra fine did not work either. Should I try a tougher clay? I also tried using turtle bug and tar remover and that did not work. I am also a beginner to detailing if you haven't guessed already lol. Thank you for any advice given. Ill try everything.
