Buy metal HVAC tape from Home Depot.

Tape a few layers over the rusty areas. If there is a huge hole, use some aluminum flashing (in the siding and gutter aisle) to cover the hole and then tape it in place. That tape sticks incredibly well to clean metal.

Spray that all with color matching spray paint from autozone.

It doesn’t look perfect, but it doesn’t look bad on the audit cameras and you’ll pass unless the garage is full of hardasses.
