Gyeon Q²M Tar

by Gyeon

We Say

Gyeon Q²M Tar is another must have product from the Gyeon range. Every bit as good as professional trade-only products, Gyeon Q²M Tar is essential for decontamination duties, as it quickly dissolves organic contaminants such as tar spots, adhesive residues and honeydew. While it's free-rinsing formula prevents unsightly white stains from forming, care should be taken to ensure it isn't used on hot surfaces or allowed to dry out. Furthermore, you should also avoid using it on freshly painted surfaces, as it does have the potential to dissolve uncured paint. In short, as long as it is used with care, Gyeon Q²M Tar is an essential cleaning product, and one that is perfectly suited to the needs of enthusiasts and professionals alike.

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.

How To Use

Gyeon Q²M Tar is solvent-based, and should thus be used neat. For best results, wash and rinse your car as usual and then, working on one panel at a time, spray it on liberally and allow 1-2 minutes for it to work. Then take a PB Disposable Towel and wipe the panel down gently to remove any stubborn nibs of contamination. Finally, rinse the panel down thoroughly with a strong stream of water before moving on to the next panel. Once the whole car is done, discard the towel (don't try and wash it, because the residual odour will contaminate your washing machine), rinse the whole car down once more and then proceed to the next stage of the decontamination process (the removal of iron-based contaminants using an iron-dissolving cleaner).
