Can't use playground sand - It clog's up the unit. The unit draws sand up and through the tube using the venturi effect. Better to use a refined sand so it doesn't clog. It works OK - Very messy, very time consuming and yes you do get flash rust but there is a pre prep you can apply afterwards to hold the flash and etch the bare metal. Atleast that's what I remember.
