This will give you precise control of your surface finish, I use triangular ceramic media in a tumbler to matt the finish of some parts I manufacture to match the WD originals,

That should be written in big bold black words. Finishing is an art itself. I believe i have invested in finishing as much money as all else together in my workshop. And am constantly piling up different machines and materials related to that.

The finest sand, almost dust like at 1-2 euro 25kg bag+mini sandblaster gun from Lidl gives me the nice matte finish for small parts. For seconds.
