Well turns out last night I ran over some sort of spray paint can while following buddies through a construction zone. This happened last night and the car has been driven since so it may be caked on a little bit

Goof off MIGHT work, but I don't know if it would be any less harsh than thinner or mineral sprits. WD 40 might even work, since it's relatively fresh.
