Corrosion can render the old moldings to be useless but if they are still pretty intact a person has to find a tool or tools that will aid in stretching the moldings so that they can be removed from the steel retainer strip that they snap on to. Once the moldings are off, a person has to find a way to pry up the retainer strips and drip rails to remove them from the wood. Removing the nails maybe possible but a person would have to fabricate a tool the would grab the head and not leave marks in the parts so they can be reused. The moldings that have a bendable lip to cover the nails have to be very carefully pried upon to spread the lips open enough to get to the nail heads. The original retainer & molding stuff is getting to be unobtainium so it's important to try everything possible to salvage what a person can.

In the event that a person has no original retainers or moldings then the next best substitute has to be fabricated to work and that's not an easy task. Nothing out there is like the original stuff. Extruded aluminum pieces can be fabricated or formed & modified for some things but the way they are nailed on is not always the same. It can require filling of each of the exposed nail heads and filling over them like regular body work & paint. It's very time consuming but it can be the only alternative sometimes.
