Gyeon Q²M Tar is a powerful d-Limonene-based tar and glue remover that rapidly dissolves bonded organic contaminants upon contact. In addition to removing tar spots and adhesive residues, it is also ideal for stripping old layers of sealant and wax protection, and for removing rubber marks after track days. Gyeon Q²M Tar is safe for use on all exterior surfaces, provided that it is used correctly. The only time caution is required is when fresh paint has been applied and has not been cured, i.e. in the period immediately after a SMART repair is performed. In such cases, the use of Gyeon Q²M Tar should be avoided as, being a strong organic solvent, it does have the potential to dissolve fresh, uncured paint.
