Hi Ed, saw that too on My Classic Car (Ferrari episode) it was a company called MMLJ here is the link
MMLJ - Leading the Industry through Innovation. There is an anti oxidation additive and they did discuss paint manufacturers not liking the soda blast media.
I paint sometimes and there is so much to go wrong before, during and after paint prep. Always new products/methods evolving who knows what our paint will look like down the road. Do your best and think ecologically drive the cars and let the chips, dings, die offs, small lifted spots all attest to how much we like to drive our cars. Things happen with use and time anyway.
