Jim-
I have several questions about your product:
(1) Since it is a "carefully controlled blend of two products", but one  of 
them (aluminum oxide) is much less frangible (therefore longer lasting)  than 
the other (walnut shells), it seems that the original blend ratio must  change 
as the media is re-used, eh?
(2) What is the recommended nozzle pressure/distance to use for common  
materials?
(3) You mention that the blasted surface is protected from rust after using  
this process. It is because of the walnut oil deposited on the surface?
(4) If yes, what is used to remove the residue prior to painting?
(5) What is the preferred method of application, siphon feed or pressure  pot?
Thanks
