Wash and dry the car first. Spray Ta Ta Tar straight onto any tar affected and leave it to dwell for around 2 minutes until you see the tar start to bleed brown. Once this reaction has occurred, wipe the area clean with a damp Dirty Deeds cloth, or rinse it thoroughly with a hose or pressure washer. More baked on or heavier tar deposits may need a second application. After using Ta Ta Tar, always be sure to seal the area with either Fully Slick or After Glow to help protect the paint.
