Custom coating kit for ultimate protection and hydrophobic performance. Gtechniq Crystal Serum Light is a coating that provides maximum performance and protection while being easy to apply, the ultimate DIY coating technology. Crystal Serum Light can be applied as a standalone product, either as a single or multi-layer coating. It offers excellent resistance to swirls (80% of protection from the original crystal serum), higher gloss level, anti-stains and surface stains. EXOv4 offers sensational surface functionality and protection and an exceptionally easy application process. EXO works on many substrates such as paint, gel coat, glass, metal, fabric, stone and plexiglass. Based on the next generation of inorganic-organic hybrid materials, it embodies the Gtechniq goal of providing products that work harder and smarter, meaning you can enjoy more time in your car, boat, plane or RV and less time waiting for it. Although this product is for greater DIY convenience, the chemical bond between the coating and your car is extremely strong, so it is important that you follow every stage of the application instructions very carefully to ensure you get the best results. This product is referred to as a “prosumer” and is therefore not recommended for people who are new in detail. If you are in any doubt about your ability to install this product correctly, we recommend you install it by an experienced detailer. Gtechniq and Roll Up & Shine assume no responsibility for problems associated with the misuse of Crystal Serum Light.
