Our silica- based quick detailer is different when compared to others on the market. One spray will go a long way- seriously, less is more! This bottle is 16 ounces, so it will last a long time. Apply with a Detail Toweland follow up with a Blue Drying towel. This is a great tool to have at the ready for quick touch-ups or wipe downs, especially when in a time crunch at shows. The silica gives it a boost of shine, enhancing the gloss. Safe to use on ceramic coatings.
