Extremely happy with the Black label.
Been using BBS for over 10 years on boat and vehicles. Only complaint would be that original BBS did not last too long on vehicles.
Black Label has fixed that.
I also think the BBS clothes helped.
1. Shady day (or just out of sun)
2. Cleaned truck with BBS (I spray it all over)
3. Applied Black label (avoided windows)
I’ll surely be getting more.
