Despite the Blackfire Crystal Seal having a great look and not attracting dust, I found something odd to me. A week later I washed the car with Ultima, dried, and then followed up with Blackfire Wet Diamond spray sealant. Without a lot of spray sealant the paint felt grabby. I also noticed that it started attracting dirt very quickly. With as easy as the Crystal Seal is to put on, and how clean the finish stays, I may just it exclusively.
