Help with rust on my Sub2000

Been Having a problem with my Sub-2000 I Loaned m car to my adopted son, and I guess he had some of his buddies helping him with a remodel and someone must have spilled water :sweat_drops: the
Moisture got on my backpack which had my Sub-200 0init and I never gave it a thought to check the back of the car, that is until I went to the range and started firing it everything was good for about 5 rounds.Then all hell broke out and after every shot thereafter the deflector stopped deflecting . I mean after every round what do you guys think deflector problem or something worse?
Right now Iā€™m thinking rust is my problem. Let me hear something back? Ok
