I just wanted to chime in here again, since I just came in from the garage with a clipboard
Narrowing products down to one line makes sense to a pro detailer who wants to streamline his setup but could mean missing out on a many great products for the enthusiast since often a single company produces only ( what personal experience and preference dictates to be)one leading product in its category to the user. The list I made below shows me that if I were forced to be exclusive to one brand, I’d go with Meguiar’s or Griot’s, but then I would be forfeiting several of my favorites.
This evening I took the time to go through my staple products. I made a list of the brands of which I use at least two. This really showed me how diverse my product assortment is because after I made this list, I had plenty of products left over that I use only one of from one brand or only one product that only one brand makes. So, FWIW, here’s the list:
Meguiars: M105/M205, D120 glass cleaner, cutting pads, polishing pads, sanding block
Griot’s: Car Wash, Speed Shine, Rubber Cleaner,Polypropylene glass wipes, Polisher
Collinite: 845 Insulator Wax, 850 Metal Wax
Menzerna: PO106, PO85RD
Leather Master: Leather Protection Cream, Leather Cleaner
Leatherique: PC, RO
P21s: Carnauba wax, TAW
Valugard: New Car Prep, Fast Finish, ABC decon wash system
4 Star: Ultimate Wheel Cleaner Gel, UPP
Pinnacle: Souveran, Crystal Mist
3M: Painter’s tape, General Purpose Adhesive Cleaner
