Crystal Serum Light is Gtechniq’s 5-year single layer application that is known for it’s durability, sheeting properties, and ease of use/application process. This product is a great standalone ceramic coating for cars that live outside and are not garage kept. Coating the vehicle with Crystal Serum Light will help keep the car cleaner longer.
EXOv4 is an 18 – 24 month top coat. This product is known for its extreme gloss, hydrophobics and ease of application. EXOv4 is a great addition when looking to stack on top of Crystal Serum Light as an additional layer of protection while adding further gloss and hydrophobic properties. I like EXOv4 as a topper, but it is also a great standalone product. I typically recommend EXOv4 to customers who enjoy maintaining their car as it makes a pleasant experience with the water behavior on the surface.
