Hidden Rust- Need to Neutralize

[jcox]

After a recent rainstorm I discovered I have a leak that resulted in the carpet on the passenger side of my "way overdue in starting restoration process" Camaro.

To make a long story short I've now taken all of the carpet, insulation, etc out and have bare metal floors on the passenger side up to the bottom of the console on the passenger side.

Needless to say the floor has started to develop some surface rust. I'm not ready to start full disassembly on the car so I need an effective way to neutralize the rust for the time being.

I've been reading up on options and they seem to range from a wire brush and then a quick coat of spraypaint all the way to POR 15. POR-15 seem like more of an option when all of the bodywork is finished but I'm not quite sure.

Any suggestions appeciated.
