Auto Finesse® ObliTARate tar and glue remover, is a solvent-based formula that quickly dissolves stubborn tar and glue residues and contamination on contact even before you touch your car. Some of the most stubborn contaminates you'll find anywhere are tar, adhesive residues, tree sap, rubber and fuel staining. Obviously, these stem from a variety of sources, but what's important is that they need to be removed from paint before further decontamination can take place. This is to minimise the possibility of scratching and marring when you move on to using clay… although, we'll get to that.
