Shocks/Calipers in blast cabinet

[OX1]

Anyone ever blast either of these and any precautions for seals. Obviously I would leave brake line on caliper and somehow seal it really well.

I blast parts like that all the time.

First reaction thots:
Shocks: if you hit the shafts at all it'll kill the seals in short order.
Calipers: if stripped-down stay off the sealing areas.

I don't think it would ever occur to me to blast either.

Yeah, shocks would be fully compressed, and it's really only the other end that needs blasting on them. Calipers are fully dressed and I have no desire to take them apart.

My main worry was if 70 grit would get in places that would do damage. I blasted an EFI EGR spacer on my dads 331 and luckily had to take off entire TB setup for another reason before starting engine. Thought I had cleaned it real well, but a bunch of grit fell out when I turned it over after removing briefly from engine. I always worry about blasting intakes for the same reason.

I blast those things at my shop every day almost. For shocks I use masking tape on the shaft first then duct tape over that and do my best to avoid that area. I have yet to damage a shock. So those are easy.
I also do brake calipers as well, and then powder coat them. I do have a wide assortment of high temp silicone plugs that I can use to keep any grit from getting where I don't want it. So far 12 years in business I have had no issues blasting any of those parts.
Believe it or not the newer valve covers that have baffles in them are harder to do than the parts you mention.
Good luck and I say go for it.
