I work in the protective coatings industry and this mixer is used with peanut butter thick two part epoxy coatings, aggregate cement polymer cements and abrasive media but it can also be used with conventional paint and drywall mortar will. The mixing action is incredibly end to end and well worth the money. It will last forever because it's stainless steel, simply sandblast it to make it shine when it has hardened material on it.
