Crystal Serum Light (CSL) is the enthusiast’s ticket to pro-level paint protection, packing up to 80% of the performance of Gtechniq’s legendary Crystal Serum. The original pro-only formula is so hardcore that it requires machine polishing with 1,500-grit sandpaper to remove if applied incorrectly, but CSL brings that extreme tech into the hands of skilled DIYers. It brings the gloss like crazy, shrugs off swirl marks, and keeps contaminants from bonding to your paint. If you’re chasing that deep, glassy shine and unbeatable durability without handing over your keys to a detail shop, CSL delivers the goods.
