Crystal Serum Light

Incredible gloss with swirl and chemical resistance for up to five years of durability.

Gtechniq Crystal Serum Light delivers premium ceramic coating protection for vehicle owners who demand a high-gloss finish and lasting defense against environmental contaminants.

This advanced silicon dioxide–based formula bonds at a molecular level with your paint’s clear coat to create a durable, chemical-resistant layer that shields against swirl marks, bird droppings, UV rays, and water spots.

Offering up to five years of protection when properly maintained, Crystal Serum Light provides superior gloss, depth, and resistance to dirt, tree sap, and wash chemicals.

Compared to traditional waxes or sealants, Crystal Serum Light offers stronger chemical resistance, easier cleaning, and longer-lasting protection.

Its unique ceramic coating formula enhances gloss over time while simplifying maintenance, keeping your vehicle looking freshly detailed for years.

Tips to achieve the best results:

- Make sure your vehicle is indoors and can stay indoors for 12 hours after application.

- Do not apply in direct sunlight.

- Only apply the product at a temperature between 5°C and 25°C.

- Shake well and wear gloves.

- Wash and decontaminate your paintwork thoroughly prior to application.

- If required, polish your paintwork, either by machine or hand, to remove any imperfections. - We recommend starting with a ceramic coat to prevent interference of debris throughout the process

- Spray Panel Wipe onto a Gtechniq MF1 Microfibre Cloth and wipe down each panel in small sections.

- Soak the application pad with 3 full measures of CSL from the pipette and work the liquid into the pad to get an even saturation.

- Replace the lid on the bottle and set aside – do not keep the bottle in your hand as this promotes premature curing.

- Apply in overlapping strokes to an area roughly 2ft by 2ft, or work to the body lines of the vehicle.

- Immediately remove residue with an MF1 cloth – you may need to buff the same area several times, but avoid doing it with too much force.

- We recommend the use of 2 cloths at any one time.

- Make sure the cloths are rotated during residue removal to prevent CSL curing in the cloth – this can make buffing residue difficult.

- Inspect the surface for residue with a bright, diffused light source.

- If you remove residue and it cures fully, you should polish the area and reapply CSL.

- As soon as you finish, put your MF1 cloths in water, wash, and dry them as soon as possible.

- Wait approximately 2 hours after applying CSL to apply EXO Ultra Durable Hydrophobic Coating or C2 Liquid Crystal.

- Store in a cool, dry place.

- Use within 3 months of opening.
