Before H2O G&G I went for awhile using Buttery on my daily as well as my non-daily. Now that I think about it, I believe it was my first foray into Adam's products
My thinking was that I wanted to re-apply often anyways, so I may as well get what is claimed to be the easiest wax to work with on the market. It looks great and water beads very well, and it truly is very easy. I'd re-apply every other wash or twice a month (seems crazy if you never detailed professionally before, but a top- up wax application can be done very quickly and still be effective).
I'm one of many self-described OCD individuals in this community but I lean towards protection vs. all-out show shine, and although the Liquid Paint Sealant is surely the best for longevity of protection, I want that "just-waxed" feeling of slickness all the time and I know I wouldn't be able to go months on a single application. Re-applying LPS seems like it wouldn't make sense, and would be time consuming. So I went for the wax.
I switched to H2O G&G for the same reasons and it's even easier to apply, with likely better protection and longevity. I suppose the shine might be incrementally better with wax, but my OCD nature doesn't extend that far even with my black daily driver. I don't expect I'll go back to the Buttery, what I have left should last me for a long time on the non-daily driver.
