best way to remove pine sap from my truck without damaging paint?

Answer 1

Pine pitch can easily be removed from almost anything by using a
water-soluble paint brush cleaner. The best thing, which is also
harmless to skin, paint and hair, is bacon grease or lard. Just rub it
on, and off comes the sap. To get pine sap off of your hands, simply
rub mayonaise on them. Then wash it off. It works great. To remove
pine tar or almost anything, apply lighter fluid, gasoline or WD-40 to
the stain. Plain old rubbing alchohol also works great.

Whatever you use, remember to wax afterwords

Answer 2

You can try the regular bug and tar treatments you get at stores, or you can try some of the things that people will say in here...mineral spirits, rubbing alcohol, etc. I personally don't know what that will do to paint and I'm not the type to just go ahead and try something, so...

I had some body work done to my car, and before I left, I asked the guys what they use to get it off since the auto-store stuff was worthless. They came out with this stuff from Ardex, and while I don't know exactly what it was other than clear, it did smell a lot like rubbing alcohol. Maybe the r.a. will work fine, but the Ardex stuff was meant for the car and paint, so I would look for that first. Maybe just call a body shop up and ask them...they know paint, so they should knnow this as well.
