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

Work as well as the NGK's
Bought for a 2016 Mazda 6, I had NGK's in it for 5 months and had misfires, didnt have the money to throw more NGK's at it for troubleshooting. Bought these to try and they work great so far.

Faulty plug? Otherwise great set
Definitely better than the old plugs that probably had 80k miles on them. The one star off is because I had a misfire after installing. Not sure if I damaged the plug or what, but a reinstall didn't fix the misfire. In my genius, I rushed to try to gap it and ended up breaking the iridium tip. Put the old plug into cylinder 3 (where the misfire was) and it was fine. Gonna have to get a new single tomorrow at my local shop, but a bit frustrating to get a misfire after install.

Upgrade from OEM
After seeing a quite ludicrous $403 quote to change 4 spark plugs in a Mazda3 I decided to show my son how easy it is. These were an upgrade from OEM parts. They were gapped perfectly for the car. They took 20mins to fit and work fine.
