Very important info on blasting with sand! If you're going to do it,
make sure you wear a GOOD particulate filter, and do it outdoors! As said, the dust gets everywhere and it'll make a mess of your shop very quickly, not to mention that you'll have the hazardous dust everywhere.
I do blast with sand occasionally (did a couple wheels yesterday) bud I do it outdoors and wear a full paint suit with a respirator. I change the respirator cartridges out for 3M P100 filters which are very effective at filtering.
