Not a lot of similarity among the three, IMO.
Flory is made with clay pigment, as I understand it. It is surprisingly fine and a joy to work with, again, IMO.
The Detailer has it's uses, however it leaves a rubbery film behind which limits it use for me, anyway.
I don't know much about Vallejo, though I have used them.
I think you will find that Flory behaves differently from both Vallejo and The Detailer.
Hope this somehow helps, Ernie.
