The alloy/aluminum can be cut right thru the anodize finish or you can remove that, polish and cut the pattern. Either way the aluminum will remain bright with any reasonable care. Wax it once in a while and it'll be fine.
The steel parts can also be cut right thru the existing blue if the polish underneath is still nice,,no scratches, dents ect that'll ruin the finished product.
Then the steel engraved parts can be left as-cut with the engraving cuts 'in the white' against the blued original finish. Or the steel parts can be run thru a reblue, either hot salt or even a couple coats of rust blue applied correctly. This to blue the engraving cuts and blend everything together. Saves a lot of un-necessary polishing, removing original finish if it's still in nice condition.
Depends on the look you want.
** If the bbl is to be hot salt re-blued,,it MUST be removed from the alloy frame and done separately. Any alloy part entering a hot salt bluing soln will simply fizzle and dissolve in an instant.
Also be careful removing a bbl from an alloy frame as the frame can crack very easily. **
The engraver may not want to work 'thru the blue' or 'thru the anodize' as it is unforgiving to unwanted cuts, especially the latter.
Also many anodize finishes don't cut smoothly and will chip at the edges of the cuts resulting in a less than acceptable result from the engravers standpoint. Some cut OK.
Leaving cut steel engraving in the white is generally no problem though if protected with simple gun maint like wax or oil wipe down regularly.
Treat it just like a blued surface,,they'll rust too if not protected with something.
