Brand new multiple clay bars for car care. Price €10 for each piece of 100g. Using a clay bar is one of the key ways to remove invisible Industrial pollution and contaminants from the paintwork if the contaminants are left untreated embedded in the paintwork for too long it will cause the formation of rust. After use, the paintwork will be as smooth as glass, no longer will there be a rough and coarse feeling which once prevented the perfect finish. At the very least vehicles should be clayed at least every 6 months.
