Down here in California, if we know whether the road is maintained by the city, county, or state.
We can call that entity & tell them what happened, they then send you to a detailing place that cleans it up, at no charge to us
the road paint is called TRAFFIC PAINT
If you decide to get it off yourself, one Counties website reads:
As soon as possible after getting paint from road stripes on your vehicle,
wash the vehicle at a pressure car wash. This will loosen and remove most
of the paint unless it has dried for more than a day.
If the car wash does not remove the paint, allow the water to dry off the
vehicle. Spray the paint residue with WD-40 and allow the WD-40 to stay on
the area for 1 to 2 hours, then rewash the vehicle. The WD-40 will soften
the traffic paint without hurting the vehicle finish. If there is a heavy
concentration, repeat the procedure.
For heavy accumulations or paint that has dried for several days, apply a
liberal coating of Vaseline to the dried traffic paint and allow to stay on
overnight. Take vehicle to a pressure car wash and wash. This should
remove most of the traffic paint. If not, repeat the procedure.
DO NOT SCRUB THE FINISH WITH A SOLVENT OR SCOURING CLEANSER
-- THIS WILL DAMAGE THE FINISH.
After cleaning the paint away, apply a good wax to the vehicle’s finish.
Wax should remove any lasting signs of the traffic paint.
Wheel wells are very difficult to remove the paint from since they are
normally a flat finish. Apply a liberal coating of Vaseline to the area and
leave for several days and then pressure wash. Applying an alcohol such
as Solox or Rubbing Alcohol to the area in the wheel well will help to soften
any residue left after the Vaseline.
