I had my white car professionally coated with Flightshield Sapphire V1 ceramic coating. I park the car outside 100% of the time. My wife gets the garage 100% of the time for her Model 3. LOL.
There is Japanese timber bamboo nearby where I park in a gated area.
Every morning, I wipe the hood with detail spray in an attempt to remove dew drops that contain sap from nearby Japanese timber bamboo.
I was hoping the ceramic coating would enable the sap to be easier removed. Ideally, the sap wouldn't adhere at all.
The sap can be nearly impossible to remove, and eventually leaves small dark ring spots.
Sadly, the ceramic coating has been completely ineffective. The detailer who applied the coating inspected the car when I said the coating wasn't working as expected, and he said the coating was only guaranteed not to allow penetrating the clear coat and etching the paint. It wasn't guaranteed to prevent sap from adhering to the car's clear coat.
Suffice to say, for us the Flightshield Sapphire V1 was a complete waste of money.
