I bought the clay bar to remove dried tree sap residues of a white car. The vehicle was a week on a tree and even after 2 carwashes went not from the stubborn tree sap. Only when the vehicle a few days in the rain was and the small resin beads aufgeplatzt (?) Are, one could cautiously begin the remains of tree resin to remove. The dough, however, has brought the least of all cleaners and detergents and demanded the most effort and power. With a cleaning glove a reputable service station incl. Insect spray it went much better. I can not recommend the dough so. For me, an expensive white elephant!
