Sorry to the Original Poster for "morphing" (AKA, hijacking") this thread from Werkstats existence to uses for Klasse All-In-One (KAIO).
I assume SOME of you still have Werkstat products somewhere on your back shelf of "don`t-use-that-any-more" car-care chemical collection/inventory/stash.
Would you still buy these products IF they were available OR if a car-care chemical manufacturer bought the rights/patents to the formulations and re-introduced them again??
Don`t worry about the thread-jack. As far as being available, rights/patents, etc....I don`t think that`s really the right perspective. From my years of observing this (and other importer arrangements) it would seem that Carlack (who has been around a long time) had no interest in establishing a US presence. Somehow, back in the 70`s, someone wanted to import the products into the US, and either that importer wanted to brand the products differently, or Carlack didn`t want to jeopardize their brand when they didn`t have a US office to oversee it, or they didn`t trust the importer...whatever--Klasse was born. Of course the Klasse products were a subset of the Carlack line.
Later, again, in a confusing way, a different importer gained rights to the newer, "nano" Carlack products, which ultimately became Werkstat (after a flirtation as Shokar with a former forum member, and current online store owner in Canada...who`s name I`m blanking on...the guy who was selling the Erazer clay until the patent ran out). Werkstat included more Carlack products, and even some custom blends.
Unclear to me why Carlack wound up with two different US importers (Klasse & Werkstat), maybe this is one of those things when lawyers didn`t run everything in the 70`s they signed a perpetual agreement with Klasse that they couldn`t get out of...or whatever. As was discussed in this thread or a different one, Werkstat for a while at the end after they ended the Werkstat brand and were selling off remaining inventory, were selling the Carlack-branded products, and even had a separate Carlack US website, and I thought Jeff (Werkstat) had just given up on the Werkstat brand and decided to just sell the stuff as Carlack (or Carlack decided they liked him and allowed him to sell it as Carlack)...but that`s all gone now. Anyway, Carlack is still in business, and I guess still isn`t really too interested in the US market. Which maybe isn`t surprising...Sonax was the same way for a while until they developed their current importer arrangement (with the company that now owns PBMG).
The Klasse guy and the Werkstat guy were both very low profile secretive operations (maybe because of agreement with Carlack), so this is all very mysterious for whatever reason. I don`t know if the Klasse guy is still alive, maybe Accumulator knows, I haven`t researched that for a long time, I think there is a very old thread here where we tracked the guy down to an apartment in San Francisco...kind of like Sal Zaino`s factory in the Mailboxes, Etc. on Rt. 9.
Sorry if I`m rambling.
