Correctamundo...
M20 Polymer Sealant has also been around for a long time, I'm confident it came out in the early 1980's and maybe even the 1970's. Formula updated as new technology introduced.
M21 is a relatively new product, I think it was introduced in 2005, a year after NXT
M20, as mentioned, is a
light cleaner/wax or
cleaner/hybrid, (hybrid = blended with synthetic and natural protection ingredients).
