Cleaning Sap Marks from Coach

I park my coach in the back yard with the front end under what I think is an oak tree. I get a massive amount of marks on the side and front of the coach near the tree. They look like a small ball about 1/32" in diameter and stick out from the surface. You can take your finger and pop the little ball off of the surface, but it leaves a round mark in its place.

I tried to remove the marks using Meguiars Car Wash and a sponge (like the ones used to remove bugs from your windshield). After a whole lot of rubbing, the marks do come off.

I also tried Turtle Wax Bug & Tar and Tree Sap Remover. It claims it is safe for clear coat finishes. I do not know if this product is somewhat abrasive, but it reminded me of a watered down rubbing polish. It also took quite a bit of rubbing on each of these spots to remove them.

Does anyone have any idea of that these marks are? Any ideas on how to safely remove them?

Thanks for any ideas you may have.

Try WD-40, it won't hurt the paint. If the sap has set long enough to etch the paint nothing will get it all off.

Try Goo Gone. It won't hurt the paint and will remove more than Goo.
Amazon has it
Amazon.com: Goo Gone, 8 Oz.: Kitchen & Dining

It's no doubt available in the Food Stores or Drug Stores.

I agree and have used it recently for that purpose.

Isopropyl alcohol is the preferred solvent for pine tree sap. Don't know what it does for oak sap, but give it a try. Harmless to all automotive paints.

WD-40. Its mild solvent properties easily break down sap. The lubricant is safe on most types of paint. Spray it on and rinse it off with vinegar and water solution. Wash as usual.

Rubbing alcohol is all I ever found that works. Wash the area you apply to afterwards.
