C1 has been independently proven in the world's most respected weathering facility. As you can see in the YouTube video below, it offers the best gloss retention out of all products tested.  Over a simulated run of 3 years in Arizona sunlight, a C1 coated panel lost half the amount of gloss as its next best competitor, and a third less gloss than the average score for all other products tested.

As well as gloss retention C1 Crystal Lacquer is extremely durable, as it actually becomes the functional surface of a car's paintwork. Also scratch-resistant, C1 forms a crystalline film which is extremely hard - this characteristic makes it effective at preventing minor scratching from poor wash technique on relatively soft automotive paint.

 

C1 coated panels have been tested against uncoated panels, as well as high-end carnauba waxes and polymer sealants.

 

On average, panels coated with Gtechniq C1, exhibited 50 percent fewer swirl marks than those coated with waxes or left uncoated.

• Ensure that you have sufficient product to coat your vehicle. For cars up to and including a BMW 5 series saloon, 30ml is sufficient but for full-sized cars including 4x4s and SUVs you will need the larger 50ml bottle
• Ensure that your vehicle is out of direct sunlight but warmer than 5 degrees Celcius, is completely dry and will stay dry for at least 3 hours after application
• When applying the product always wear gloves to prevent C1 coming into contact with your skin
• Dab product onto the application pad
• Replace the lid on the bottle and set aside - do not keep the bottle in your hand as this promotes premature curing
• Change the application pad after 3 to 4 applications of areas no bigger than half a car bonnet. If you do not do this, you will feel the coating becoming sticky when applying, this makes it extremely difficult to buff
• The coating forms an almost immediate reaction with the paint/fiberglass molecules it comes into contact with. The reaction time of C1 is temperature and humidity dependent "“ for normal room temperature at around 50 percent humidity, we recommend buffing between 30 and 60 seconds afterward
• You may need to buff the same area several times to remove residue. We recommend using two microfibre cloths at any one time. Please note that you are only removing excess product
• Avoid buffing with too much force as this can spoil the surface you are protecting, and you may also drag the partially cured coating off the surface  
• Take care that the microfibre cloths you are using are rotated sufficiently and quickly so that C1 does not partially cure in the cloth, this will make buffing residue significantly more difficult
• If you miss removing residue and it cures fully, you should re-polish this area, and reapply C1
• As soon as you finish put the microfibres in water and wash and dry them as soon as possible, otherwise, C1 will crystallize in the cloth  
• Allow the coating to cure for at least 12 hours before it gets wet
• Use C1 Crystal Lacquer within 1 year of purchasing
• Store opened bottles in a dry and cool storage area that's out of direct sunlight
• We recommend only using opened bottles within three months of opening
