Yes Goo Gone is safe for auto paint and has been deemed safe by the manufacture of the Goo Gone to use on automotive paint surfaces.
I've used Goo Gone to remove tree sap and any other sticky substances from my car and trucks paint and it never harmed the paint.
The Goo Gone removed the sap and anything else sticky from my car and truck without harming the paint.
When I used Goo Gone to remove the sap from my car and truck I had a bit of Goo Gone residue leftover on the car and truck.
To remove the Goo Gone residue take a cloth or sponge and soak it in some laundry detergent such as Dawn Dish soap and then wipe the car down.
Then just spray it with a hose and it should come off.
