I'm not adverse to buying more/different shot for the job.
I need to clean up engine cases, so I don't want to do anything radical, but I want a nice finish when I'm done on the exterior. So, is a multi-stage shot an option? I understand it's not like sanding, where you start with a corse grit and move to a finer grit.
I haven't used the glass yet - I'm also wondering about recommended PSI/CFM. You can tell I've never done this before.
