If you are talking about the 7075T6 receivers, you can anodize and dye them yourself... much better than painting.  If you do paint, however, don't strip the old anodize... just paint over it.  Blasting will definitely damage the anodizing.

If it were me, I'd strip the anodize with lye (don't leave it in too long), clean, sandblast, anodize and dye.

4 ozs of finish should be enough for 3-4 lowers.

Norrell's strongly recommends AGAINST bead blasting. Sandblasting is preferred.

If the lower is already finished, then you don't have to sandblast, just apply the finish over the existing finish. If it's raw aluminum, then sandblast it.

I've used it on a SIG and the finish is as advertised. Works well and seems to be very durable. Do a search on Google for 'norrell moly resin'. There are a couple sites that give complete instructions so you'll know what to expect.

Does the Anodizing/dyeing work as well with other types of forged receivers, or the cast ones?

The anodizing works but the forged receivers take the dye much better than cast.  An option with cast receivers would be to clear anodize then paint... that way you get the hard coat.
