I have removed tar residue with WD-40. It will remove the gooy stuff on bottles and jars too. It will also knock a wasp out of the air and either kill it, or give you time to kill it.
The WD-40 will not hurt your paint on your car, so it is well worth a try.
Live in the city. Someone took their boots to the side of my auto, leaving black scuff marks. WD40 worked like a charm to remove.
I got hit by a basketball pole........and it happened exactly like it sounded.....I was in my driveway and started my car and the wind blew like extremely hard and the B-ball pole fell over and struck my car leaving a punishing black scuff mark and some little paint damage. but I tried everything to remove the black marks. Any tips? I know they will come out but how and with what!
depending on what the black marks are from, try using an eraser.
