I need help with restoring my Famicom

[GoodNoodle]

Hey,
I'm restoring some of my old consoles and the first one is the Famicom.
I retr0brighted it, but the color on the back came off.
The metal sheet on the controllers is pretty scratched.
And the eject button is scratched as well.
Does anybody know, how to fix that and where I can get spare parts

How much are you willing to spend? Because you could just buy a Junk one for parts if what you need for yours is in better shape on the parts one. You can also find people selling controllers online as well. As far as the back part, I'm not sure if those can be removed and replaced using a heat gun or something similar.

I'm willing to spend some more money on it because the Famicom was very cheap and works very great.
But I would say 50 bucks is the limit. But I've seen a lot of Famicoms on eBay for 20 bucks, that are in good shape but defect.
I will look into buying one, thanks for that Idea!
For the back part. Is it possible to buy stencils for it and repaint it?
