If it's completely hardened, I use a razor blade and carefully scrape it off, then go back over it with isopropyl alcohol. Works good, but you have to be careful.
I was taught a long time ago Pine-Sol dissolves the sap like magic and cleans up very easy. And no chance it will harm the paint, even single stage paint.
Maybe for Indiana trees, but not Georgia pine. That stuff is like JB Weld when it dries.
I always use rubbing alcohol. Works great. It will take the wax off. So I usually just do a quick wax job after.
Same here....to bad there is not a way to bottle this stuff....
