I was a zaino biggot for quite some time, but I never (yes I mean never) got the application of the product to go on without streaking. Yes, I tried all the tricks posted here and elsewhere and even talked directly to Sal. This was, just so you know, prior to the Zfx additive and perhaps that could change things. Nice finish, great optical clarity but there was that one issue that I could not get around. There was also the drying time per coat of this and that. Way too long . Remember, this was pre Zfx.
Bottom line is, I tried
Klasse based upon many of the postings here, and never went back. Why? Seems that
AIO works very well, and the
SG, when put on super thin, is reasonably easy to use. Protection seems great, and clarity is indistinguishible from Z to my eyes. To boot, it is less money. Money, by the way, that I dumped into
Souveran, because, well, I was dumb. OK. OK. It is great stuff, but not anything that I can see a difference between say S100 or something like that. I just wanted a wetter look, and I liked the combination. When the Souveran runs out it will likely be replaced with the less expensive S100.
I also agree that Klasse seems to attract less dust. Again..MHO.
