Baked on tree sap

Um...what happened to that first one? I usually encounter sap in very small droplets, not big globs, but that first one looks really weird--obviously from the scratches around it you have already worked on it.

As others have said generally a (mild) solvent is indicated for sap.

If you don't have any luck with above methods you can use a razor blade or a plastic one. I have used razor blades on paint to remove vinyl and would likely work but you gotta be extremely careful. It is already scratched so it's gonna need polished anyways.
