My all-time favourite Bondo Queen was a Ferrari 275 GTB that appeared on the FerrariChat website several years ago. It looked so-o-o-o pretty (and cost the new owner about $1.5 Million at the time to make the pivot from 'just shopping' to 'proud new owner'). Nevertheless, he decided to commission a shop to make it 'even better' (including new paint, of course). Unfortunately, when the shop started to prep the body panels for said new paint job, they discovered evidence of filler in places where it shouldn't have been. Digging deeper (literally), they found that the entire nose was nothing more than Bondo. Up to 1" deep in many places. More exploration (excavation?) found deep pockets of damage that made one think that the car had fallen off the top level of an auto hauler and landed on its roof. The shop was stunned by quality of the bondo slinger's work, calling him an artist. When we made the transition from horses to autos a century or so ago, the method of transportation may have changed but the same shysters stayed loyal to the cause and moved from 'horse traders' to car retailers without losing a step.
