Thank you. Beautiful work. I never understood when to use the carbide. In place of what grit? Also, was that a nova Point you were using at the end? Looks like Green which is a 60? Seems you would need to polish higher at that point.
The green bit is a silicon rubber bit impregnated with very fine diamond, I can't quite remember at the moment but i think the green is 400 or 600 grit.
