Not a cheapie dust mask, an expensive dust mask. That and a face shield and your good to go. When you finish soda blasting use air to blow all the dust off and prime as soon as you can. Blasted surfaces start hazing with rust fast.
soda is too soft a blasting media to remove rust an scale , but for a nice gentle blast job with out putting too rough a profile on the surface soda is the way to go . I have had a couple corvettes soda blasted pryor to restoration an it didnt even damage the jellcoating .
