I'd try one of the "Bug and Tar Removers" first. It's designed not to damage paint or clearcoat.
Maybe some WD-40 on a micro-fiber cloth?
Either way, I'd follow it up with a good wash and a quick coat of wax when you're done.
Denatured alcohol is the solvent in your bug and sap removing products.
If you have a can of lacquer thinner around DO NOT USE IT except to Q-tip it directly on the sap itself.
Lacquer thinner will eat paint. Kira
