The guy was very nice It just seemed he was reading from a cue card his reply was exactly what is written in there q&a. I guess I expected specific dilution ratios for different uses like mckees n914 and adg wipeout does. I enjoy griots products and I’m not bashing them. I’m just sharing my experience with what the original poster was asking.
Part of me wonders if they don’t recommend it at stiffer dilution ratios for other uses so they don’t steal sales from other (more expensive

) products. If it’s lubricious enough to be used for wash, I’d be surprised if it couldn’t be slippery enough for clay lube duty/etc.
The stuff reminds me of N914 (though honestly I like the Brilliant Finish better). You could try mixing smaller batches to try out and see what ratios you like best. I frequently do little ~8oz spray bottles to play around.
Haven’t had a chance to check out the video Visitor shared. But my thoughts - For presoak, you could riff on the N914 ratios, bumped up to reflect respective Rinseless ratios. You could also try it at the 15:1 like the Rinseless Wash and Wax, or I think you already did the math for If Rinseless Wash and Wax is 320:1 at Rinseless, or 15:1 for presoak/waterless, and Brilliant Finish Rinseless is 128:1 at Rinseless, then... crud- math’s not my strong suit. But I think your math checked out earlier.
If you wanted to use it for purposes other than pretreat at stiffer dilutions, you could always start with it on glass and see how it goes. I’ll confess I’ve mixed up Brilliant Finish at a stronger ratio and I use it for windows - works great. I’m kicking myself for not writing down what ratio I did.
I think you’ll like the Brilliant Finish if you haven’t used it yet. So many variables come into play, but lately I reach for it vs N914 if I’m going leave-nothing Rinseless. I got Uber when it was a big forum favorite - it has a nice look, but I’ve gone away from using it because I swear it leaves the car a dust magnet. Sorry to jump off topic there, but let us know what you think!
