There is a 12 page thread on the sister forum where the F product above was compared to several other top tier RW/WW products
The folks who first tested it got thrown for a loop because it was so strong it was killing sealants and waxes
At first they thought it was leaving something behind that was simply masking the beading and sheeting on sealants and waxes but they finally figured out it was stripping them
It didn't touch ceramic coatings because that is what it was designed for, prep before coating and maintenance of ceramics, which it apparently does very well
As Klasse pointed out above, they found the suggested dilution ratios are plenty, this isn't an "I will add 2 more glugs to the bucket" product
At one point everyone was pissed and ready for refunds but it finally dawned on a few people that hey, here is the strip wash we have been looking for so we can apply something new or fresh to bare paint, and hey, here is a top notch panel wipe for pennies per gallon, and man does this get all the film and toppers and stuff off my ceramic and let it do its job
One of the best things they all realized is the dilution ratios on this stuff are so huge that it is incredibly thrifty
Guys were figuring out a liter would last for years plus it isn't expensive to begin with
They also figured out it is an amazing presoak for microfiber
I have a liter on the way, unfortunately the USPS is in their normal

mode and it is stranded somewhere between California and Hawaii...
When I finally get it I have a number of uses planned and a fresh gallon of DI water waiting to be turned into panel wipe
I am excited to try it to prep for my 3in1 which is also supposedly on the way
YMMV
