I was wondering whats the big deal with using Aluminum Oxide with this unit?
I bought one for playing around with powder coating parts for my Autocross and Street cars. I know what happens when you use glass bead on Aluminum parts then go to Powder coat them (pin holes from glass popping out of the pores), but the manual definitely recommends against anything other than poly or glass.
What will happen if I use AlO2 in it? Wear out the nozzle? No biggie.
Eat through the sides. That would be a problem.
I would fear static build up more with poly/ glass than with Oxide. 😮
