I found the best stuff that I have ever seen to remove tree sap from Pine Trees. We were camping 3 weeks ago and had sap on the hood of the Pilot, we (I) tried wax and grease remover and variety of other things to no avail. I took the Pilot in for its first oil change to the dealership where I bought it and pointed it out, they told me to drive it over to the detailers when I was ready to leave and they would be happy to remove it for me. This guy brings out this stuff in a red aerosol can, I believe it was called Xenit (my memory is terrible, but I will double check on this this week since I will bring in my truck to have some more sap removed from its hood as well), he sprays the area and wipes a few times and the sap was gone, I have never seen anything cut through sap like that. Great stuff!!!
