Car Wash-I have two gallons of ONR, but I promised my Dad some, so that leaves me about 1.5 gallons, maybe 6 weeks?
QD-don't use QDs very often, have a gallon of Quikshine, and a half gallon of Optimum Instant Detailer, should be good for a year or two
Tire Dressing-Have a half gallon or so of the 3D Protectant, be gone in a couple weeks
Interior Dressing-Just got another gallon of OPP, ought to last me 5-6 months. Almost out of Leather Vital, need to get some, 1/3rd bottle of Meguiars Interior QD-last me a month or two
Polishes-Quart of HD Uno, new bottle of Optimum Hyper Polish, half a quart of Meguiars #205, almost full quart of 3M Ultrafina, half bottle of Optimum Hyper Compound, nearly full quart of Meguiars #105, half a quart of Optimum Finish, half bottle of Meguiars #300, 3/4 bottle of #301. Should be good for 3-6 months, just depends on how much polishing I have to do.
LSP-Almost full gallon of Optimum Car Wax, half full bottle of Opti-Seal, a tin and a half of Meguiars #16, nearly full tin of Collinite 476, quart of HD Poxy, 2/3rd full can of Glanz Wax, nearly full jars of Souveran and Paste Glaz (and no, not parting with ANY of my Paste Glaz), nearly empty jar of Wolfgang Fuzion, a pint and a half of Clearkote Carnauba Moose. It would probably take me several years to go through what I have.
Just got a 5 gallon container of 3D carpet shampoo, based on the 16:1 dilution ratio, I may be retired before I run out!
