330 GTC Rust repair

The GTC project is getting some attention after sitting idle for a few weeks. The car is very solid but suffers from the same problem as all Ferraris which is water getting trapped between layers of unprotected steel and corroding it away. The GTC has a very elegant circular vent in the “C” pillar to let air pressure out of the cabin when the doors are closed and when the vent system is used. Since this vent is an open hole into the interior, a little catch tray with a drain pipe is attached to the inside of the pillar so water doesn’t ruin the headliner and flood into the interior. A hose that can be seen under the car allows this tray to drain onto the ground but over time it plugs with debris and the water builds up and leaks inside the rear fender arch making the car disappear into a cloud of brown dust.

Understanding that this car is 45 years old, the bodywork is in amazing condition but you can see the concentrated rust damage connection to the leaking “drip tray”. The front of the rocker panels is rotten away which makes sense because of all the water spray getting inside while driving in the rain. Pininfarina did a great job sealing these car up when new and we will follow their technique so when we’re done, we’ll use the same super thick and rugged seam sealer (that smells like Star Wars Action Figures) allowing the car to last another 50 years when we finish with it.

    Ok, now I have to go smell my Star Wars action figures. And I also want to know what the stuff is? Sounds useful.
