Thanks all. I agree that they do seem miniscule and my wife has often says I am too picky when it comes to these things so I decided at the time to continue with the assembly. I cooked some wings on it the next day and it performed flawlessly.
I did email Weber and they are sending a replacement bowl. They, surprisingly, got back to me very quickly (like after a day).
I guess I have a backup bowl should this one decide to rust.
