I’d oil it and leave it as it is.
OR
get some nitro paint, mask off the edges plus say three inches in on all sides and spray paint onto the body
like an anti-relic
Relic fans normally take paint off, you’d be putting it right back on ... keep going and it’ll get closer and closer to showroom condition
seriously you’ll never get this look again so I’d fettle it and fit everything and spend some time thinking exactly kind of paint it really needed
