Brand new flagstone, recently sealed with Creosote wet sealer AND I got green Rustoleum overspray paint all over the stone and the line of the drop cloth is visible! I am sick-stupid!! Hopefully the sealer prevented the paint from being absorbed by the stone. I read mineral spirits and a hard bristle brush and elbow grease for untreated flag stone. Would that also be the remedy of choice for my sealed flagston? OH, PLEASE KICK ME! Thanks for any remedy treatment you offer!
