I told my father-in-law about this thread, and the experiment- he is a retired chemist.
He seemed to know what the abrasive would be in the 'real' clay and had ordered some before for some lab something or other..
Of course, the minimum order was more than ten people would use in home-made custom-mixed clay in a lifetime of daily supertanker detailing-.
I think there are really finely refined bulk abrasive powders used in the field of amature telescope mirror grinding. It's gotta be some good stuff to make a mirror smooth finish on a MIRROR! ha!
If I can find some, I'll be posting the result here.. but i'm not in a big hurry to
I can imagine it now- detailers sharing recipies for home-mixed clay.. 'In a base of three packs of handi tak, add 2g of xxxx aluminum oxide and 7g 6x pumice- and to make it stick less add a pinch of un-perfumed talc'
I doubt anyone is hell-bent enough to save a fist full of dollars on some clay by tediously mixing optical grade abrasive powder into some packs of handi-tak- but you never know. If it worked, may be a good cottage industry for a shut-in.
"Earl's hand-mixed custom abrasive car clay-- In color-specific blends!"

-class war breaks out between those who detail with 'premix' and the purists who blend their own.
Think there is no market for such a crazy thing?
