if its DOT stuff , it has alot of plastics in it
is it DRIED completely?
you may be able to get a plastic razor blade and peel it off, especially if the plastic had some protectant on it
try mildest means first
HOT soapy water, soft cloth
or wd 40 on a cloth and saturate the paint, then try how soapy water again
you can use acetone, CAREFULLY wipe in one direction and do not over saturate the area, followed by HOT SOAPY water and rinse
mineral spirits may also work, again do not over saturate and rinse with hot soapy water followed by clear water rinse
