For me, I only have a couple at the moment as I'm trying a bunch of new cleaners/polishes/waxes/sealants to break the mold for a bit. A couple of mine for example would be Stoner's Glass Cleaner, Meguiar's Natural Shine Interior Detailer, and Meguiar's #26. Stoner's cleans glass like no other, Meguiar's Natural Shine leaves the best looking, non-greasy, lasting protection I've seen, and Meguiar's #26 is some of the best looking off the shelf pure carnauba wax I have found. Don't get me wrong, I loves me some Menzerna polishes, but like I said I'm trying to branch out so I won't be listing those. I'm omitting the obvious here of clay bar, wax-safe shampoo, buckets, PC, UDM, etc. But, I'm curious as to what everyone's must-have's are in terms of any cleaning/polishing/waxing/sealing/shining/protecting products. List what they are, why you absolutely need them, what they do for you, and some pictures are always welcome
