Non-X- or Y-rated caps may develop resistive leakage paths internal to the cap body upon exposure to AC line spikes. Repeated spikes can and will decrease the resistance to the point where significant power is dissipated by the leak. The cap will get hot and eventually catch fire or set something nearby on fire.Your friend's tweak would be a good way to improve the outer insulation of a cap that had to be used at a high voltage with respect to ground, and may improve the sonics by reducing the acoustic response. However, it will not affect the internal leakage issue.
