On diecast parts like CJ valve covers, distributor housing, and fuel pumps it depends on how rough the previous blasting was and what media was used. If glass beads were used, the colors and sheen can be restored, but the surface will not be quite as smooth as when new. Previous blasting on rough surfaces like intake manifolds doesn't hurt anything.
