I would not overthink it. The $7 Meguiars gold class 48 oz jug only needs 1 oz per wash. That's 48 washes for $7. that 15 cents/wash.
Comare that to the local pressure washer place where it takes $1.25 just to get the sprayer blowing.
I've used it for years on my 2007 Tacoma in dark blue (shows scratches easily). no buildup to speak of. If you drive long enough and want the silk smooth finish feel of new paint you NEED to claybar before waxing. The little brakedust and other stuff you pickup at highway speeds embeds into the paint and have to be physically removed. (thats what a claybar does) You only "need" to do that every year or so. not too often and it is optional.
I also like to use a microfiber mit. Microfiber has lots of little "pockets" to grab grime and hold it.
You never want to scrub hard on paint. Water is a very good solvent on its own with no help. hose the car down and let the water loosen the dirt before washing to make your job easier.
I like Megs better the blue coral as I notices a difference. The blue coral didn't seem slippery unless I put a heavy dose in the bucket. Like glug glug heavy. meg get just as slippery with very little. I dont care about suds, it just want slippery so the mit slides easily across the surface.
