#120 Aluminum Oxide - 8 LBS - Fine Sand Blasting Abrasive Media for Blasting Cabinet or Blasting Guns.

work great with my cheap sandblast gun

Works better for GunKote than the Alum. oxide from harbor freight, but its also more expensive, so choose your poison....

I tried using it with a simple gun. It works perfect - compared to a regular sand it takes not just old paint off but also stubborn rust as well leaving shiny metal. But using it with a gun is way too expensive...

Works great for blasting paint and scale off cast iron parts
