Using seam sealer on the top will be helpful if your car leaks through the hood seals like mine does some times.

That certainly does help. The grade of metal used for the replacement panels is really good these days, but for extra insurance I still wire brush and hit that internal cavity with POR15 or the like before welding the tank support. Better than nothing.
