I made the mistake of claying my car in 90 degree weather, in direct sunlight, which left a clay haze (actually melted clay residue) all over my car. This took a couple hours to correct by spraying detail spray and wiping every square centimeter of the body panel. This also made the clay bar start to disintegrate in my hand, but again, completely my fault. I learned my lesson and will only clay a car that doesn't have hot body panels and is parked in the shade. The bar was big enough to cut into 4 sections, which was good because I did inadvertently dropped 3 of the sections on the ground while working. Once you drop a clay bar on the ground, you need to throw it in the garbage so that you don't drag ground debris (rocks, dirt, etc) across the paint. Again, user error played a part in this because the panels were so hot, the bar would grab as I was rubbing it across the panel and it would slip out of my hand. Aside from all of the mishaps, whose fault rested completely on my shoulders, the product was great. As far as the end result, my paint and glass was left so incredibly smooth that it was like baby's skin. I was so impressed with how well this clay bar took every imperfection out of the paint surface. I used diluted ONR,nbsp; OPT Optimum (NR2010Q) No Rinse Wash Shine - 32 oz. nbsp;as a clay lubricant. After claying the car, I followed that up with a paint sealant on every inch of the exterior (glass and lights included, but not wheels), using Wolfgang Deep Gloss Paint Sealant 3.0 in thenbsp; Wolfgang Deep Gloss Combo 3.0 nbsp;and the shine was beyond words. See for yourself in the attached pictures. I plan on claying my car about once a year and would use this clay bar again...with all my lessons learned the hard way.
