6mil Gunbroker Receiver refinish question

[Brinks352]

I saw this 6mil receiver on gunbroker.

My question is if you where to repark/refinish the receiver would the stain/blemish still be visible?

I look forward to the responses.

I'm looking at it on my phone, but looks like a little rust and maybe some pitting

I think that would come out perfect.
