I would suggest a preliminary chemical treatment prior to the sand blasting.
The reason for this line of thought, is that mine has rusted badly in the floor, even though it was white blasted, cleaned, primed and painted, all on a fine dry day. I believe the armour plate forms large holes inside,from tiny pin holes at the surface, that the blasting process has no effect on.
