The bitumin stuff in the rear footwells doesn't follow the contours of the floor very well.
Water gets into the cutouts, and sits in the gaps until you get rust, so you may be better off removing it.
Me and my brother spent a whole weekend welding up my last 156, which was particularly bad. Not only were the rear footwells rusty it had rust on the inner sills, spare wheel well and the front inner wings.
Considering it was only 8 years old at the time I was pretty dissapointed, and it put me off Alfa's for a while.
You will never be cool driving a Vauxhall.
