ideas on how to treat floorboards

[714x4lover]

WELL BOYS IM IN ARIZONA , ONE OF THE DRIEST PLACES IN THE COUNTRY, AND MY DRIVER FLOOR AND KICK PANEL ON THE DRIVER SIDE BOTTOM FLOOR IS PRETTY DERN RUSTY, WHEN I GOT THE TRUCK 12 YEARS AGO THE KICK PANEL WAS ALREADY RUSTED THROUGH AND THE FLOOR HAD LIGHT RUST ON THE FLOOR PAN BUT NOW THE FLOOR PAN IS REALLY RUSTY AND STARTING TO GO THROUGH LIKE I LIVE IN THE SALT COUNTRY. I ALSO HAVE A LEAK SOMEWHERE BEHIND THE DASH BOARD. ANYONE KNOW WHERE THESE LEAKS COME FROM SO I CAN FIX IT.
