Crystal Serum Light is an excellent DIY, stand-alone coating offering unparalleled gloss and gloss retention through its superb resistance to wash swirls. However, its water repellency falls short of what EXO has to offer. Therefore, if you want the best for your car – remarkable swirl resistance and water repellency, then this kit is definitely for you.
