On this we can start a speculative thread.... The best answer I can come up with starts with a statement of fact: "Unless proven through reproducible and defensible scientific studies, the data discussed is pure anecdotal speculation"
There was a time when Dawn soap was said to strip all LSP off the paint, till it was proven otherwise. It was speculated for years that claying would remove all impurities and strip the paint until it was proven otherwise, and paint cleansing polish are said to strip wax/sealants until a flaw in the "facts" is brought to bare. To totally strip your LSP you need to understand the bonding of said layer. A natural wax produces a very weak bond, whereas the hybrid wax produces a slightly better one, which is then followed by old school sealants and nano-tech sealants. Now we have nano-ceramic impregnated sealants which are said to offer the greatest bond longevity (if you don't count coatings). Each of those product will require an increasing degree of chemical or mechanical "force" (or both) to break that bond.
So what is the answer?? As the acronym goes, YMMV (your mileage may vary). You will have to test each method and tweak it based on the known limitations of your prep, maintenance parameters, age of the product, environmental exposure etc.. OR you can throw the book at it (ie. chemical and mechanical stripping). This involves a wash with an alkaline pH soap, mechanically claying the paint, IronX treatment if needed, mechanically polishing the paint and chemically cleansing the paint.
