Why use Gtechniq Crystal Serum Light?

Crystal Serum Light is the prosumer version of the world famous Gtechniq Accredited Detailer Crystal Serum Ultra. It offers 80% of professional Serum Ultra’s performance, but if applied incorrectly can be machine polished from your vehicles paintwork.

When it comes to adding gloss, resisting swirls, contaminant and dirt repellency, Gtechniq Crystal Serum Ultra and Serum Light are the pinnacle in paint protection.

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.

The high density ceramic layer is resistant to chemicals ranging from pH2 – pH12. This characteristic also makes bonded contaminants such as tree sap, tar, and hard water spots, easy to remove.

Unlike mainstream wax and organic polymer coatings, Serum Light can resist much higher and lower temperatures. Temperatures as low as -40­° to as high as +250°c.

Crystal Serum Light comes with a 5 year guarantee when applied by a Gtechniq Accredited Detailer.

Application information

– To apply Crystal Serum Light (CSL) 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
– Spray Panel Wipe into 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 you MF1 cloths in water, wash and dry them as soon as possible

Stylish and practical backpack for work and travel
Color: Upgrade-apricot, Size: 15.6 Inch, Color: Upgrade-apricot, Size: 15.6 Inch
For both everyday work and travel, this bag has proven to be an excellent option. I can feel secure bringing my computer around because to the 15.6-inch laptop compartment's solid fit and ample padding. Notebooks, chargers, and a few personal belongings can fit in the spacious main compartment without feeling crowded. The apricot color looks polished but still casual enough to wear outside of work, and I really enjoy the sleek and fashionable shape. Even when the bag is completely packed, the straps remain comfy, and the stitching seems sturdy. I particularly enjoy that there are several pockets, including smaller ones for a phone, pencils, or keys. It makes everything accessible and well-organized. If the material gets a bit dusty while traveling, it washes clean and the zippers open smoothly. It is lightweight, adaptable, and functions well as a carry-on, purse-style bag, or business backpack. All things considered, it's a good everyday bag that is both practical and stylish.

Perfect for a backpack or a purse
Color: Upgrade-black, Size: 14 Inch, Color: Upgrade-black, Size: 14 Inch
I love this black backpack. It has gold zippers and brown accents and it has a pocket in the front two on the side three inside and a pocket on the back of the laptop pocket. I have a disability and have to carry extra stuff so this is a perfect size for me to wear in my back every day. It’s black nylon so it should stay clean. I tend to drop things. I think this will be great, but even without a disability, this is a great backpack. It’s so cute.
