Death of a C4 Corvette – Cash for Clunkers Style
The Cash For Clunkers law requires dealers to destroy the engines of the trade-in vehicle or face a $15,000 penalty. The US Government provides step by step instructions on how to do this.
The government’s approved method of disabling a car states that the engine’s oil has to be replaced with sodium silicate, also known as liquid glass. When the car is run with a this mixture, the liquid quickly evaporates and the sodium silicate is left behind, causing most of the oiled surfaces inside the engine to seize and break.
This video shows a perfectly good Corvette being destroyed by this method.
