75 Duster Tetnus Shot and band aids

I started removing the undercoating on the inner fenders. The right fender has a lot more damage on the inside of it from rust than previously thought. Upper inner fender wells where the fenders sit will need repair. Lower radiator support will need to be replaced. Ordered from AMD Bottom of frame rail on drivers side is ripped open just behind where the lower radiator support attaches. The pile of black stuff is the undercoating from the right side inner fender
