Whats the best way to strip what I think are pot metal parts, specifically headlight extensions, 1/4 extensions, fast back vents and the "corral" surround for a 65 fastback?

Can I glass bead them safely? Should I turn the pressure down? I usually bead blast at 100 psi+, but i was usually doing rust removal off of steel.

Should I pressure sandblast outside on this 60+ day in the north east? 40 psi ish?

Should I do something different?

Thoughts appreciated...
 
Those sail panel vents have some sharp style lines to preserve, I usually chemically strip them and brush off the paint, it may take a few applications, then wash with water well and lightly sandblast them, shoot a few thin coats of epoxy.
 
I blasted the 1/4 extensions for my '68 Cougar. I have a cabinet with a pressure pot mounted on the bottom. 60 grit aluminum oxide at 40-45 psi. I strip just about anything this way.
As Bob said, I would be careful with the fastback vents. I haven't had to deal with anything that delicate.
