so they basically achieve the same results as one another, just one is made for applying in a high humidity atmosphere?
More or less... depends on how D.O. you want to get...
M05 dries white, that's not clear.
M07 dries clear
If you were wanting a non-abrasive polish to maximize the depth, clarity and gloss, then you would want a product that is clear, not opaque or white.
From what I have read on this forum, Show Car Glaze is a new and improved version of New Car Glaze.
That to my knowledge is incorrect. I've written on the other topics you've brought up but I'm only going to address the first portion...
I've been told by the head chemist at Meguiar's that he's never touched that formula and it's been unchanged since it's inception. That would put that formula date back to the early 1900's, between 1901 and probably 1920, I don't have an exact year, I don't know anyone that does know the exact year, not even Barry Meguiar's because I've asked him before as well as Ken Meguiar and neither new they exact year.
M05 came out in the 1950's as state previously.
The link I included above both have pictures of bottles and my best guess as to the origin of M07 and everything I wrote implies early 1900's
I've never heard or read anywhere where someone that would actually know has said M07 is new and/or improved.
The label was changed as I've also documented, but not the formula.
If you really want to have a good understanding of these two products, or their cousins, then get real-world hands on experience by adding them to your tool chest.
