I have a black car an its parked outside3 24/7 so I get alot of tree sap. There are small dots all over the hood roof trunk and top of doors. I tried clay bar and it only take off some of the sap, i am guessing the ones that cane come off are the ones that are baked on. I also tried isotopy alchole that was recommend by a buddy but no work. Anyone have any other suggestions? Should i take it into body shop and have wetsand and polish? or hire a detailer?
