decoration text is missleading

see https://www.reddit.com/r/feedthebeast/comments/bjmtrm/futurepack_grinding_surfaces_of_metal_blocks

It says that I can grind the surfaces of metal blocks to make them plain and simple, but there is nothing about how can i do that.

its airbrush, you can paint with it and remove paint bu putting sand in it, but it only works with decoloring colored metal blocks and other stuff, it doesnt work on a metal block

I fixed the text for this to make it less ambiguous.
