I did it a couple of months ago and do not see any damage to the finish.

It was not on there very long because as soon as the sap was off, I washed off the orange cleaner.

Don't know if it would matter but the part with the sap does not have a clear coat. The suburban paint was peeling on the top of the hood and top of the cabin as was common in 1980's GM products. Those areas were repainted a few years ago and the painter said he did not apply a clear coat. I don't remember what kind of paint that he used.

Alcohol worked on the tree sap too but was very slow.
