I would talk to a good body shop for advice before I do anything if I were you. There's Dennis McCoy at Allen's Auto Body in your area that has always given me full satisfaction. Better be paranoid than sorry...
Call John Whitmore at Automotive Enterprise in Belmont/San Carlos. I have known him for years, he is the GM there and will be able to make the right recommendation.
Greg:
From one Jet Black owner to another. If the "glob" is big enough, put ice on the sap until it is rock hard. Pick it off with your finger BEHIND a soft terry cloth. If you have wax on the car it may pop right off. If any residue is left, try a very small amount of mild dish detergent such as Ivory liquid in water to cut the rest of it. REWAX that spot immediately as the detergent takes the wax off. I have tried Dupont's bug and tar remover which is pretty much just mild kerosine. It works great but I would try something less invasive before going that route. If you put the bug and tar remover on your big glob, the tar remover will smear it all over. Try to get as much off before putting the cutting agent on it. You'll have much less of a mess.
I have tons of pine trees all around my house, so I am used to having sap on my cars. I have found the easiesst way to fix this is to use a clay bar. It requires vertually no effort, and the spots are gone within seconds. Try motheres clay bar, zymol, etc.
RESULTS: Well, I was intrigued by the "ice" idea. Tried it - worked great! The sap became hard and brittle and chipped right off with only fingernail. Left a tiny bit of residue which a little polish cleaned right up - but no smearing of sticky goo to ruin your day.
