AMMO sounds like it's pretty good stuff. I've actually had my eye on their Boost product...will probably order some soon to try out once the weather warms up.
I use mostly Meguiars products (which actually is what Larry used and still uses), but have bought AMMO stuff to support him for his videos, and because he has some products that no one else has.
Boost and Hydrate are phenomenal, and have no competitors, AFAIK. I went from getting basically no suds (due to hard water) to a generous amount, and hard water spots are much less abundant and severe. Hydrate takes some getting used to, but works very well once you get the hang of it.
Reflex is another unique product - needless to say I'm very happy with it. Unfortunately it didn't go as far as I had hoped - but my trim really seemed to soak it up, so that might be it.
I've also picked up the Interior Regimen - very happy with all that as well, tho I think you might be better off with cheaper stuff in general. I didn't want to skimp on my leather treatment tho.
