There is two spray rust inhibitors that I will recommend here to the Bolters and I have had excellent results with them in eating away rust. I removed most of my screws on sheetmetal with a screwdriver or 1/4 drive socket. You must let it soak for a few minutes to up to 24 hours depending on how bad it is rusted.
