Crystal Serum Light is the pro-summer version of the world-famous Gtechniq accredited detailer Crystal Serum - a coating so hard that if applied incorrectly can only be removed by using 1,500 grit sandpaper. 

Crystal Serum Light offers 80% of professional serum’s performance, but if applied incorrectly can be machine polished from your vehicle’s paintwork. When it comes to adding gloss, resisting swirls, contaminant, and dirt repellency, Gtechniq Crystal Serum and Crystal Serum Light are the pinnacle in paint protection.
