Well right now I'm in the market for tire shine, some kind of leather treatment, I need a new clay bar, other than that I'm pretty much set
I use Bold n Bright by the gallon. It is an amazingly diverse product and absolutely one of the best tire shines, interior and engine dressings available. Poorboy's Leather Stuff is top shelf as well. I use it in my BMW and all of my client's get the same treatment. It smells like authentic leather not some chemical by product or fruity toothpaste and most importantly it contains UV protection, is not shiny, nor greasy.
