Message :How much material is safe to remove without risk?

it's a process that removes microns (ie, measurable, but barely) of material.
when you send it off for extrude hone, the most they will remove will be 1/16 of an inch at worst.
everything will end up a highly polished finished.

the more passes they make with the 'clay', the more the process costs... making the greddy or pentroof exhaust manifolds look pretty damn good.
