    Gtechniq CSL Crystal Serum Light is the prosumer version of the world famous Gtechniq Accredited Detailer only Crystal Serum Ultra - a coating so hard that if applied incorrectly can only be removed by using 1,500 grit sand paper.

    Gtechniq CSL Crystal Serum Light offers 80% of the Professional Crystal Serum Ultra'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 Ultra and Crystal Serum Light are the pinnacle in paint protection.

    Gtechniq CSL Crystal Serum Light forms an ultra-durable, high-gloss, slick to the touch, chemically bonding inorganic layer of 9h optically clear ceramic. Once applied, gloss levels will remain in the upper 90th percentile for significantly longer when compared to traditional paint protection products, and cleaning your car will be a breeze.


    • 1x CSL 30ml or 50ml
    • 1x Pair of Nitrile Gloves

    • 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
    • Spray Gtechniq Panel Wipe into a 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 bodylines of the vehicle
    • Immediately remove residue with a microfibre 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 you microfibre cloths in water, wash and dry them as soon as possible
    • Wait approximately 2 hours after applying CSL to apply EXOv4 Ultra Durable Hydrophobic Coating or C2v3 Liquid Crystal
    • Store in a cool, dry place
    • Use product within 3 months of opening

    Protecting any car cannot get any easier!

    CSL light is the easiest ceramic coating to apply.
    Take your time ensuring the polishing and correction stage is done correctly followed with a panel wipe down.
    Trick here is ensure your surfaces and work space is clean and for first time users read the instructions take your time and the results from all you hard work will be rewarded and your car will be well protected.

    Highly recommended adding GTECHNIQ EXO coating as a topper this makes the coating which is already very slick, even more slicker and the beading is incredible!
