Resin from tree leafs- possibly? what do do
Seen some comments on here for the cleaning off the black marks but I wonder if there is a solution for what looks like a sticky resin perhaps where leaves have stuck to the van over the winter. I used Auto Glym resin polish today, but to no avail, so bit puzzled, maybe need more elbow grease but the marks are very stubbon. When you look along the side of the van you see the resin marks even after the appliction of auto glym. Be grateful for any advice. Thanks in advance
