I've used silica sand for decades, gonna stop using it since it's not so safe.

What is the best overall media? Doing mainly rust removal.

i use evapo-rust. on small parts not too costly. about 22 dollars a gallon. on large items like manifolds and oil pans i also use bricks to take up the voids as will use 5 or more gallons so cost is over 100 dollars. i did use sand and also soda but got in it every place it could go. the advantage is after soaking for 2 days based on weather and temperature the item can be cleaned with water. brush it off while in the liquid first. use a long wire brush.

I use 80 grit aluminum oxide in one cabinet and glass beads in another.
The AL ox is a more $ than sand but creates less dust. I still use sand outdoors when pressure blasting, but with a respirator.

sl*g products like Black Beauty are what I use. Little more money but low dust. Still need a respirator. Also doesn't contaminate the surface like sand can.

I've used crushed auto glass, silica sand and black beauty.
About 15 years ago I purchased a ScatBlast cabinet and vacuum from TP Tools.
One of the best investments I ever made. I'm still on the first set of sleeves, but have a spare set on hand. I have all the consumables on hand as spares. I found out that the plastic film the local HyVee uses to protect fresh flowers works great as a liner to protect the window from getting all cloudy. I wipe the dust off the window with a damp towel, let it dry and tape a piece of the plastic on the inside with 3M blue masking tape that doesn't leave a residue. Needless to say, the women in my life got flowers, they never knew why.......kills two birds with one stone....

I have a gravity feed canister blaster as well, I've built a tent inside my "shop" out of poly sheeting so I can blast larger objects. I wear a paint respirator and a hood when blasting in my tent.

I have found that plastic removes paint a lot better than glass and glass removes rust a lot better than plastic. That was from cleaning parts in a cabinet.

That's interesting vinny,

I'll have to get plastic media, what source have you used to buy the plastic beads from?

Does the plastic prevent heat build up and warpage in thinner gauge sheetmetal as well ?

I don't remember where they got the plastic from. Plastic would take the paint off very quickly to the cad plate. After that the glass would get rid of the cad plate and clean out any rust. 

I saw a very expensive aluminum part get destroyed with plastic (would have been destroyed with any media) when the guy wasn't watching what he was doing and had the pressure too high.

I have good success with crushed walnut shells. Don't seem to overheat like some of the other medias.

I use glass beads for the material that isn't terribly rusted and where I want a smoother finish.  I use the medium aluminum oxide for the tougher stuff that requires more cutting power.
