Just another B&B blend to his liking. 95% of these spray sealants are similar. Some are unique if you're looking for specific qualities like extreme hydrophobicity. G3&1 is still one of the best in terms of durability. OK to use but not great.
Some that are unique to me:
Fireball Duke Show Car Wax
Kabita Signature Wax
Collinite Beadcoat
Polish Angel Cosmic Spritz
Sonax Ceramic Spray Coating
