I have a 1987 camaro , while changing out carpet I found some rust hole's under the drivers seat and a 4 inch round hole infront of the driver's side rear seat. The passenger side floor pan is in very good shape, just a little surface rust. What can I do to halt rust in it's track's ? I know welding a new drivers side floor pan in is the preferred way but have no access to a welder. Any other repair ideas? How much can I expect to pay to have patche's welded in? Any help will be very much appreciated.

 

If you have the tools, you can paint over the rust will some rust inhibitor and rivet in some sheet metal for a temporary fix, but in the long run, you'd need to get the rust cut out and have some sheet metal welded in it's place. And some rubberized undercoating would be a good idea, too.

 

Sand down all the surface rust, weld in patches for the holes. And POR-15 your whole floorpan.
