Mark, here's why I questioned your advice:
...A true car polish is not something you want to use on a regular basis since it actually removes a very thin layer of the clear coat or paint (although not nearly as much as rubbing compound, which should only be used once on a very old and oxidized paint service)...
No, true polishes are non-abrasive, merely creating a bright shine a wax then adds to and protects. A polish like Meg's Ultimate Polish can be used everytime you wax with no ill effects whatsoever (assuming it's applied correctly). Quality compounds, like Meg's Ultimate Compound, are also very mild micro-abrasives (SMAT) that you'd have to go well out of your way to do any harm with, like using lots of pressure and staying a long time on one spot on a plastic painted bumper, for example. Otherwise, it can be used everytime you wax, though it might not be necesary, depending on swirls, etc.
...Meguiar's Cleaner Wax...probably [does not] need to [be] used on a continuous basis for the life of your car (unless used sporadically). Probably OK to use a product like this one time when the car is new (after paint has cured) and then follow-up with a traditional wax product after that.
Misleading. Paint on new cars is already cured by the time we buy them, and (although I haven't used MCW in a long while) you can use such a product every single time, and probably need to if all you're otherwise doing is old school waxing, because just washing and waxing will not be good enough after a few months to a year of gunk building up on a daily driver non-garaged, especially if you're only waxing once a year because you think wax lasts that long
...Most decent modern car waxes no longer actually contain natural waxes, but are actually synthetic polymers. True waxes (especially carnuba wax) are typically only used on show-cars to provide visual depth, but they don't last very long and are easily removed with a detergent...
Well, there is less real difference visually between any wax compared with another, even on a black car, than some people seem to think. The real differences are in the prep or condition or polish of a panel or area. It also depends greatly on what "detergent" you're talking about.
...Synthetic polymers have sealant properties and have the ability to physically bond to the paint or clear coat that most people are looking for, and last a reasonably long time. They are so hard to completely remove (unlike a true natural wax), that body shops have to use special chemicals to remove it when repainting a car.
Misleading. It sounds like you are talking about those dealer sealants which are more akin to clear coats, and that is not the same thing at all as a synthetic wax.
...One-step sprays are typically used on a wet car (right after a car wash but before it is dry), but these typically don't last as long as the kind you apply, let dry, and wipe off. But they may be OK in-between regular waxing, especially if it is the exact same brand/formula of liquid or paste wax that you used previously with traditional application methods.
Sorta, as least with Meguiar's. Quick Detailer is a non-abrasive cleaner-polish for water-less washing, Quick Wax is a non-abrasive booster for the proper wax, and both should be matched to your wax's product line, as you said.
...One of the problems I had with advice from "professional detailers" is that they often use products that are buffed with professional buffing machines, and that is not something most car owners want to do for themselves.
You no longer need a rotary buffer to get that look (which carries more risk of paint burn). You do need a 3-step process, though, and a DA is definitely the way to go. I remove product and buff by hand, although, I might get a buff pad here soon. Still, professional detailing advice is not something to ignore just because you don't want to use a machine (if I understood you, correctly). Some detailers can surely be wrong about a lot, but I've been very impressed with the Meg's forum.
...I
don't believe:
- That a carnauba wax will last nearly as long as synthetic. Perhaps Meguiar's carnauba waxes are blends of carnauba and synthetics, and they last longer than pure carnauba.
- That a good quality synthetic wax lasts only about 5 weeks as you imply above. Most good synthetic car waxes will last up to year, depending on how often they are washed and what kind of wash detergent is used.
Yes, Gold Class is a blend, some others aren't. Some people in the forums report NXT lasting as little as 3 weeks and Deep Crystal as long as 6 months, and of course, the reverse, and so on. Again, it totally depends. I'd used a synwax before (First Place Finish) and it only lasted a few weeks at best, but then I was washing a lot. I've used others over the years, and not washed as much, and never got anything like a year out of them as you're claiming. Now,
the basic polish or finish itself (not the wax) can certainly last a long time. I mean, if paint is in great condition and washed with a quality wash-n-wax soap, you can sometimes barely tell the applied wax has actually worn off. I really don't think anyone is getting a year out of any wax job, unless it's a garage-kept car under a soft cover that only comes out for a few hours at a time and thus never needs much actual cleaning

For us DD'ers, the "finish" might last a year, but the wax would have long since washed off.
...But I use a car as transportation, and I am not obsessed about how much it shines. I also don't have a black car, which needs a lot more attention.
Yep, so it all depends on how it's prepped, how it's driven and stored, washed, etc. In my case, my goal has been to basically stop washing the car unless I really have to. Since
changing my gameplan, I'm using the "duster" and QD/QW now, saving water, time, effort, and of course more work correcting swirls from the washing.
It's been two weeks since I corrected the Coupe and I see and feel no loss of wax yet. Just today I did the 3-step DA correction on another car and the feel of the two paints is the same, that velvet-like near wet feel. The Coupe has been rained on several different days, driven in the rain and sleet, and been out on the interstate a good bit. I've not washed it the old way in two weeks, and have only applied QD/QW three times. The gloss factor is the same as when I'd corrected (stunning!), and the same as the other car today. I'd say another few weeks is no problem at all, maybe 6 weeks total or more - but I might re-correct before then, anyway. So, we'll see
