Beware!
Look under the dash board of your car(Drivers side). Take a flash light if required. Have a good look around properly. You may find unpainted steel structure and maybe rusted too. In other words bare steel surface, bare welding joints will also stare at you maybe with rust gathering around the joints. Same with the brackets that hold the dash board. Chances are that you will be shocked by the gory site of RUST having settled in . . . . and maybe you would want to wake up and think of having done something.
Go ahead have a look gentlemen before it is too late.
