Repairing rust in the Plenum Chamber

It was soon discovered that when the FB Holden got into the rain or was washed the passenger side floor would flood.  Although offering your passengers a free foot bath when you are cruising in the rain may be appreciated by some it most certainly is not appreciated by all.  It was decided that the rusty hole in the plenum chamber of the Holden would be repaired and as the seats, carpet etc… had to be removed anyway in order to modify the floor hump to suit an automatic gearbox the rest of the floor would have any rust removed, and it would be treated with our rust deoxidiser then sealed.  All in all giving a much dryer and warmer drive in the FB Wagon.
