The Lusso doors were in pretty good shape, but because the door skins are aluminum and the door frame is steel, electrolytic corrosion tends to take place wherever there is moisture. Water tends to collect at the bottom of the doors and this where bubbling will occur on new paint job a few years down the road. Scaglietti or Pininfarina sometimes used primer, and often times used nothing between these surfaces, but after over 40 years, it’s time to address these surfaces.
The Panel Shop cut the bottom edge of the door out and fabricated a new piece of aluminum to weld into place.
The old piece is showing signs of corrosion which would have eventually rotted through. With new epoxy sealers on the steel and aluminum surfaces, the owner will have a paint job that will not bubble at the bottom of the doors.
