No it isnt a spray on product.
It is a 3 step wash, one consist of an acid, the second base and the third is a neutralizer if I recalled correctly. It can remove rail dust and pretty much any other bonded contaminant. It is more or less a shop cost saving alternative to clay. I have heard many good things about it, and Ron K. is a great detailer, so they have to be good.
FMINUS: Since you are in SoCal I think your distributor is:

ValuGard is the proper spelling,

probably the reason you cant find it.

I have no idea who came up with that spelling hahahha.
EDIT: I am not 100% sure on the acid base part...I might be confusing it with something else. but I do remember that you MUST seperate A, B and C!
