The upper jackpot supply chute and the jackpot dump chute are made from tin as are some other parts. These have surface corrosion on them. I gave them a surface scrub to get off the easy surface corrosion, but they still don't "look good".

Typically I scrub off the surface rust so that it won't flake off, but no more than that.

I'm not usually worried about the back, since I am primarily concerned with getting it clean and functional. But when you look at the back of the machine, it doesn't look "restored" because the corrosion is still there.

I'm not sure what bead blasting is. I don't have a lot of resources since I am an apartment dweller, so I'm doing as much as I can given that I don't have a "work shop".

I guess I should be satisfied with what I have since the machine works and the front looks good.
