Just found rust on my floorpans....what do I do?

What started out as a subwoofer install has left the interior of my car bare. I first removed the hatch panels b/c they need replacing and tonight I pulled out the front seats, carpet, console, and shifter. All this b/c there is some rust on the floorpans behind the front seats. There are two small holes (pin holes). I going to add Second Skin Spectrum and Damplifier pro to the car for sound deadening but need to address the rust first. How?

I know I can sand it out and prime it but Ant. from secondskin told me about a product that you brush on the rust and it converts the rust into a metal like substrate. It doesn't strengthen the floor but stops the rust. Is there something like this that will strengthen the floor too?

What would yall do?

cut it out, weld in a patch, have done in numerous times, not a big deal really. Go and get a 67 mustang if you think yours is bad

Well overall its not that bad. I've done a search and saw that someone recommends fiberglassing it. I just wanted to get some more opinions.

I guess Saturday is a little slow on the boards.

I just got back from local auto parts store and was looking at a Duplicator product that changes the rust into black primer. Anyone use it before?

I've decided that the holes are small enough that I'm just going to fiberglass it.
