Ok, so thought about this a little more since I didn't have time yesterday to do anything.
Maybe I'll get a small blaster and stuff to do this as I might have a few other parts along the way and need it anyway. I had one when I started this project forever ago but don't know what happened to it.
If I did go with the walnut shells, which grit? I've never used walnut shell...do I need to protect anything with it?
Any tips?
