Hey everyone I thought I would share my experience with applying CarPro CQuartz coating on my leather seats today. I have the dune interior with nappa leather. I wanted something to help protect the seats from stains since I have young kids. I wasnt willing to pay an arm and a leg for the “protection package” offered by the dealer. I found this CQuartz product for $60. It supposedly is a “semi permanent” coating that helps prevent stains and dye transfer. Most reviews online were positive. I first cleaned the seats and honestly after two months weren’t dirty as much as I thought they would be! The CQUARTZ went on well with the cloths they provide. A little bit goes a long way and I found the trick was to do smaller sections with less product. Then immediately after applying an area taking another rag and wiping the area down to smooth out and fill in any missed areas. It did not add any shine or “slick” feeling to the leather. It looks shiny for about 10 minutes until it dries. I used about 2/3 of the product provided to treat all 7 seats and steering wheel. Took me about 1 hour and 45 minutes to clean and treat the leather (I was being meticulous to hit all areas and ensure even coverage). Again I think the biggest piece of advice I have if using this product is to immediately wipe down with the extra cloths they provide and smooth out the application. For $60 I figured it was worth a shot. Will keep y’all updated.
