I second the SPI epoxy advice, and yes you can spray any primer surfacer over it or any topcoat and the epoxy itself is also very sandable after full cure is reached. High zinc phosphate content. Very good stuff.

For a sandblasted surface there's absolutely no need for a 1K self etching primer, in fact some self etch primers shouldn't be sprayed over a sandblasted surface.
