Hey Alvin,
I am not a detailer, but I have had the same situation and remedied it with satisfaction. I used some kerosene on a rag and gently dabbed it on the pitch places. Let the solvent work for a few minutes and then gently wipe it of with a clean rag moistened with kerosene. The pitch should come of relatively easily. Kerosene wont damage the paint or clear coat. To be safe, avoid doing this in the hot sun or on a real hot surface. You will need to reapply wax to the treated areas.
