Yup. I'm at the same point. I have so many products just for my two vehicles. Pretty much everything I ever wanted to try.
Sometimes it feels like an addict's rationalizations...or like in Animal House with the angel and the devil on Pinto's shoulders:
Me: I've got enough tire dressing to last for years, I shouldn't buy any more until I use up what I have.
Devil: Here's this thread about TW tire coating...they say it's really good and it's cheap!
Angel: You already decided you don't need any more tire dressings
Devil: But this isn't a dressing, it's a COATING
Angel: But still, it's a tire appearance product, you have plenty of that
Devil: But this lasts SO much longer than a dressing
Angel: Who cares? You have plenty of dressing, just put it on more often
Me: But on the backs of the tires, I only dress them when I rotate, and it would be so much easier to clean
them if the dressing lasted longer
Devil: That's a great idea!
Angel: You don't need any more tire appearance products!
Devil: But they stopped making the TW, if you don't buy it now you'll never be able to get it!
Me: They did?? I'd better order some...
Angel: But you have tons of tire dressings!
Me: But they aren't coatings! Can't you see I need this!? (clicking order button)
That's how I wound up with the Ech2O and the Reset, I rationalized to myself, even though I have tons of conventional, rinseless, and waterless washes, I didn't have any SiO2-enhanced washes or stripping washes, so I NEEDED these...
