Both!
Example 1:
You want to make sure that it would get no rust on it!
Example 2:
If left out in the rain, it would get rusted.
Depends on what sentence you are using!
Neither one. It would rust is correct. Rust can be a verb.
Depends upon the context of the sentence.
would get rusty
or
would rust
or
will rust
or
can rust
"would get rusted" seems to me that you would be mixing a future state (would) with a current or pasted condition (rusted). Rusted is a current condition. Would implies that something hasn't happened yet. Something is rusted now, it won't be rusted later; it will rust later.
i agree with howard. it would rust. you dont say, it would get rust. you could say.....get rusty.....
Which is correct? 'would get rust or 'would get rusted'
