Every external body panel was sanded clean. Mostly with a DA. Yes I've used glass beads extensively, but only on "hard parts" like hinges, brackets, nuts and bolts. Yes leaves a slight "texture". On a side note... high build primer does wonders.

Glass on the aluminum steering box and nothing but a tarnish preventor clear coat.
Again, glass blast, but a coat of my mixed Semi Gloss Tremclad. Springs are glass blasted and T9'd.

There are 2 types of glass, crushed glass and glass bead. Crushed glass is from recycled bottles, it's cheaper, but it's only meant to be used once. Glass bead can be re-used and is good for cabinet use (I use it in my cabinet), but is more expensive. I used white silica sand in the past, it was a great all purpose media. It took off rust well enough, but not too aggressive, and gave the part a nice satin sheen. I would try and stick with media that doesn't have silica in it unless you have a good ventilation set-up. That leaves out all types of sand. The cheapest option would probably be crushed glass at about $10 bag.
Here's a link explaining the dangers of blasting and crystalline silica dust:

This would falsely lead one to believe ventilation isn't important with other media.
The simple fact is anything but air going into your lungs is a hazard and when blasting with any media a well sealing mask is an absolute necessity. Keep in mind its not just the media that's a hazard but the crap you're blasting off as well. Unless you're using a blast cabinet obviously.
Stayed away from glass beads. It scares me. Soda blasting gets into cracks and can cause rust latter. Hard to get out. Bought a harbor freight sand blaster and used a low grit sand. If too large it plugs up the system. Did a lot with wire wheels and small sanding disc from harbor freight. 2-inch disc on a right angle die grander. HF sells different grit ones. An argues task for sure. Frame rails use a bottle wire brush on a piece of fish tape and welded chain on the tape to run in and out of frame rails and the rockers. Once cleaned out got a bed liner gun from East wood. With two different wand's that would get into those areas. Applied rust converter then put a good coat of epoxy primer in those areas. Then shot bed liner in everything. Just what I did and don't think I will regret what I did. Jut my two cents. Good luck on the work.
