Whatever stuff I`ve had on the shelf for over a decade and want to use up

Heh heh...sorry, couldn`t resist...but actually that`s the truth. And I`ve had my current stash for well over a decade.
(Regulars here know that I like very low-gloss tires. That in-between matte and satin, "fresh from the mold" look.)
I simply *LOVED* the old version of Z16 and used that, still have some left too. But I`ve heard the current version is quite different and I doubt I`ll try it.
Among the others I`m using up is Griot`s Vinyl & Rubber Dressing. I think I`m down to my last gallon now...like how it looks, but it does need redone pretty often. This product looks like it`s gone bad...dark, some gross floating globules in it...I mean, really *really* gone bad, but it still seems to work fine. (Heh heh, I can`t imagine any other Autopian using something so obviously gone-bad, but hey...)
The other I`m using up (have maybe a gallon of it too) is Pinnacle`s stuff. It`s *really* old, mid-late `90s. Like how it looks too, but it`s another than needs redone frequently. This stuff has *not* gone funky the way the Griot`s has, seems just like new. Downside is that even though it "dries dry" and doesn`t feel tacky at all, dust of all kinds seems to be more of an issue than with the Z16/griot`s; cleans off OK, but they just get that "those dusty tires need cleaned again" look awfully quick.
No idea whether the current versions of the Griot`s and Pinnacle are the same stuff.
I expect I`ll try the non-slick Duragloss product if I ever use up what I have now, but that really is an "if" because I use it up so slowly.
