I didnt watch the posted video, but if the individual performing the blasting is based out of California, I think he's from Germany? and knows his stuff. One of his videos takes you through the equipment involved and cost of his equipment. Some of his videos have oily greasy crusty garbage covering driveline assemblies and it cleans them beautifully. Also, I saw a comment about rubber and or plastic damage-- once again, watch all the videos related. It makes the material look brand new and does no damage.
