so my MBP was being repaired, I get it back with a nice scratch in the bottom (most likely from screw driver) it's deep enough and is a gray line I can feel, it's in the bottom, doesn't bother me, but can this lead to future rusting in that area?
Got a tip for us?

A scratch in the bottom of my MBP, will this lead to rust?

No. The outermost layer of the aluminium will have oxidised by now - protecting it from interacting with air any further and rusting.
Technically - it's rusty already. In fact every part of the aluminium on your MBP went rusty seconds after it was first pressed into shape.

Rust being ferrous oxide and the casing being non-ferrous, I believe the chances of that are middling to low.
So scratch away and dunk it in water. Your safe.
From rust at least.*

Should be fine if you give it a few seconds in air for the topmost layer to react with the air and form Aluminium Oxide which will protect the aluminium underneath from reacting.
Put a thin layer of zinc on top of the Al of your MBP it is the sacrificial metal after all.
Just kidding, nothing to worry about.

I've had a scratch on mine for over a year. Other than the pain of knowing it is there, you have nothing to worry about. Plus, aluminum doesn't "rust", but it does corrode.
"Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum, so it isn't as easy to notice as rusted iron."

So what you're telling us is those of you who have MBPs should scratch them up the wazoo and then they will end up being better than before?
It came back that way from repair? I would throw a fit, that is completely uncalled for.
Usually if you can prove that they scratched your machine, you can write a formal complaint into Apple asking them them to replace the damaged part or request a exchange. A service provider should take full responsibility for any damage incurred (with the exception of your data) regarding your machine whilst it's in for service.
