Today I tried 845 after washing and drying my car. It already had UPP and Optiseal and I wanted to top it with 845. My first observation was that 845 smells like Raid bug spray and it has a really oily feel. It felt like I was putting olive oil and solvent on the car. I let it haze for about 15 minutes and then I removed it. It was very a difficult product to remove compared to all other sealants and waxes that I have used in the past 10 years(and I tried a lot of products). I hope it lasts a while because this product is going way in the back shelf of my detailing products and I hope the solvents don't remove my layer of UPP. I was not too impressed
