Quoted from BlackCatBone:
I use crushed walnut media and add to it Flitz,
I used the walnut media without anything like flitz and after 4 days nothing. I have some flitz and will try again. Do I rub flitz on the spring then put it in the vibratory bowl?
The plating didn't do so well, that's why I'm short a spring.
Everyone here has been very helpful, I can't offer any advice as a pay back unless its plumbing related.
