Re: bright zinc plate cover coating
Blue chromate leaves the item with a hint of blue and provides reasonable protection.
Is the part subject to much heat or wear?
If not you can always polish the zinc finish and then clearcoat with a good quality laquer.
If you polish zinc to a mirror finish without breaking through it, it is quite durable anyway I zinc plate and polish OEM exhaust heat shields and they hold up very well.
