Hi,

I’ve been using cartridge rolls, greaseless compound, etc. to smooth factory castings such as aluminum intake manifolds. Extremely time-consuming.

I’ve heard that perhaps I could use glass bead (or other media) blasting to accomplish the initial smoothing of the rough surface, prior to beginning polishing.

Is this the case? If so, what media/pressure etc. do you recommend?

Thanks.

Mike
