Glass bead works really well. I thought about buying the Harbor Freight unit but instead purchased a similar bench top unit from Eastwood. Before and after pictures below for reference.
How did you mask off the innards? I really don't want glass beads up in my cam tower.
This. Can't speak for the 944 manual, but Haynes manuals are notoriously awful for a lot of other vehicles, especially anything that isn't a mass-market car. Anything that looks questionable I try to confirm with a second source.

Assuming they're correct. When they're not, it can be a costly assumption.
The first time I learned this, it resulted in a cracked aluminum coolant flange.

Right, never blast anything that you're not sure you can remove 100% of the media from, because it WILL find a way in no matter how well you think you plugged it up. For example, a master cylinder.
Any sort of milled or polished gasket surface should also be masked.

I very carefully taped all the openings and the sealing surfaces with blue painters tape. After blasting, I removed the tape, rinsed everything thoroughly with soap and water and blew it out with compressed air.
Here are the steps I took:
wire wheel as much as possible (makes it shiny)
glass bead blast the nooks and crannies (makes it white)
clean in dishwasher (makes it dark grey)
For the lettering, I then sanded starting at 80 grit and going up to 2000. Then I buffed with an angle grinder and aluminum polish. Probably could have done better but the buffing pad was getting eaten up.
so now I know I can polish, I just don't think I want to polish all the nooks and crannies to a chrome finish. Will consider options. I just did my manifold in wrinkle red, so I could match that, but that's a lot of red.

And after some polishing and clear coat. These things can clean up really nicely!

Nice job. Hope you don't use that oil in your car though.
