We are doing the car for a customer. We decided to post photos to show what needs to be done with a rusty car, wether it is a Maserati, Ferrari, or Bugatti. We have seen so much poor work being done and this could help someone to see what they should being seeing on their car. If you look at the photos of the original floor, it was undercoated over bare bare metal from the factory. When the undercoating breaks there is bare metal exposed. Also when these cars were built they had no primer or undercoating on the inside panels, hence the rust issues. We will have no bare metal when finished, all inside panels and boxed sections are coated with industrial epoxies. When the cars are done this way they do not have to be done again. Hope this helps someone.
