Projects | BMW 328i | Single Stage Correction | Cquartz UK Coating

This Montego Blue Metallic BMW 328i came in the shop for our single stage paint correction service. It was riddled with swirl marks, light scratches and RIDS (random isolated deeper scratches). We started the detail off with our decontamination process by spraying the wheels with Sonax Wheel Cleaner Plus and agitating with various brushes. The tires were cleaned with Turf Shine Tire Cleaner Concentrate at 50/50 ratio and the wheel wells were treated with Sonax Multi-Star APC at 10-1. The painted was washed with Chemical Guys Citrus Wash and decontaminated with CarPro Iron-X and a Nanoskin wash mitt.

For the cutting portion of our correction process, we decided on a Rupes UHS pad paired with Meguiar’s M100 on the Rupes LHR 21ES at speed 4.5 for most of the panels. This combination cut away most of the light defects but a few RIDS still remained in the finish. We switched over to a Meguiar’s Microfiber Cutting Disc and M100 on the hood and trunk to remove some deeper marring.

We finished the paint down with Sonax EX-0406 on a Rupes white pad on the Rupes Duetto. This combination restored the slight compounding haze left over and left a crisp finish to lay down CQuartz UK. After the polishing process we rewashed the vehicle with Dawn followed by 2x IPA wipe downs to ensure all the polishing oils were removed. Next, we applied two layer of CQuartz UK to all the paintwork.

The CQuartz UK Edition (aka CQUK) is a specially formulated version of the popular Cquartz Ceramic Quartz Paint Protection. This edition is based on the same technology as the regular Cquartz, however it has a few slight improvements for cold temperature application, and specially for the UK while it works great anywhere. CQUK has 70% SiO2 with 99.9% purity, making it the first ever nano silica coating which has such concentration! This high purity percentage ensures having the most transparent glass coating over the surface, high levels of water repellency and long lasting paint protection from dirt, road salt, ice, snow, and other environmental contamination.

We cured the coating with IR heat lamps at 150F for about 8 minutes per panel. After the panels had cooled down we applied CarPro Reload to the paint which adds an additional layer of protection while also enhancing slickness and water beading properties. We finished the wheels, trim and glass with Reload as well to round out this detail.

Nothing better than some nice sun stars!
