Soda also does not remove rust. I use SPI primer and they will not warranty their product if you use it over Soda Blasted metal. Soda Blasting leaves a residue that is crucial to remove for adhesion.
This is from the tech sheet for my epoxy primer.
"NEVER use SPI Epoxy over a Soda Blasted vehicle, Acid Etch/Wash Primer, Rust Converter or other Metal Treatments. NEVER!"
