Bead blasting leaves residual compressive stress in the surface. In some
application this is a good thing but on thin flat items such as clutch
plates it may lead to warping. I agree with Mr. Sayegh, better not to bead
blast clutch plates.

I know many people recommend this but I don't go for it. Although the finish
after bead blasting would be great, the chance of warpage is also there. I
have
owned a bead blaster for most of my life and you would be surprised how it
can
warp a piece of thin metal. I avoid using it on precision small or thin
parts.
If you decide to do it make sure you use very low air pressure.
