Oak and ficus sap in Crescent Park and Old Palo Alto
The heritage oaks and ficus lining Crescent Park, Old Palo Alto, and Professorville drip resin onto cars parked on the street or in open driveways, and on bare paint that resin bonds and begins to etch within a day. A ceramic layer keeps it on the surface, so it softens off with a wash and never gets the chance to stain the clear coat underneath.
