Anyone uses Carlack 68 Sealant?

[Bonifax]

Hi guys, I just read that Carlack 68 sealant is one of the most used sealants in Europe and was wondering if any of you have used it.
By the way, someone told me that Carlack 68 and Klasse sealant is virtually the same formula?

Carlack AKA Jeffs Werkstatt

Carlack, Klasse, and Jeff Werkstatt all come from the same place. I believe Jeff being the more updated formula of the three (I think, not 100% sure though).

Klasse twins are the original Carlack offerings. The newer Werkstatt formulas are most like 68 and designed from Carlack as noted. Still quite finicky to use and remember this is NOT the carnauba Werkstatt offerings but the Acrylic offerings.
