What Savage MK2 bolt parts to duracoat?

[shaman]

I've put several hundred rounds through the gun and several hundred more bolt cyclings at home. There is a lot of missing bluing on different parts of the bolt. I plan on taking the gun out to the 50 yard line for another bulkpack worth of shooting this weekend and then send the necessary part off for duracoat after cleaning.

But, what parts do I need to send?

I had my bolt on the 455 cerakote and it feels very gritty, probably gonna take a long time before it gets smooth again
