The application was easy for this coating. It flashed almost instantly for me. So the removal was tricky. ( done in a garage at 68 degrees). The bottle I received was sealed nicely. There was no expiration date noted. I bought the 10ml version. There was some crystallization on the neck of the bottle. I was worried the product inside was affected. I used the whole bottle on a hood of a vehicle. 3 coats applied. Hood was prone to water spots before. The layers dried very glossy, and candy like. This coating leaves a smooth, slick finish. Just bought another 10ml for the roof. Vehicle is a large SUV%u2026..

I absolutely appreciate this new formula. The application is even easier then the UK version in my opinion. Flash times vary. No more then 3 to 4 minutes here in the North East. It's leveling/removal is simple. It doesn't leave high spots that aren't seen. I've gone through over 250 ML of Sic with outstanding results. Time will tell how long it lasts. With many vehicles coated with both UK and the original formula. The Sic leaves the finish the smoothest and like glass. With over 30 years of detailing experience. I absolutely love CQuartz. My only complaint is that when opening the bottles. You lose maybe 3 ml due to pressure. No matter how slowly I opened it. Not sure of the fix. They also should include more of the white clothes. Other then that. Buy with confidence.
