Body and paint SOS-911 help

Whatever you do, DON'T sandblast the exterior panels of the car. They will warp the panels and be a big mess.
Media blasting with soda, walnut shells, or something not as aggressive as sand will strip the paint off of the exterior just fine. Even if you turn the pressure down on sand and ''fog'' it at the car, you will still run the risk of warping the panels as it is very abrasive and builds up a lot of heat.
Sand blasting works good for wheels, frame rails, and strong areas of the body, not on thin flat panels like the side or the roof of the car.
I know what it's like to be older and try to do things you could do easily when you were in your 20's! It's all about pacing yourself. Know your restrictions and deal with it accordingly as well as pace yourself.
I hope this helps, and good luck with your project.
How about some pictures?
