So I parked under a tree with those small yellow leaves on it. Then it rained. I didnt use the car all weekend and by the time I got back to it, the car was stained all over by the leaves. I ran it through a new gas station car wash (yucky I know, but I was desperate and its new)and they are still on there. Should I attack them with a bug and tar remover or do I need to get more serious?
