The issue is what Henry Ott calls "the invisible schematic hiding behind 
the ground symbol. Wires have resistance, and that resistance results in 
modulation of V- at the radio when operating SSB.
And the three power supplies I own, all purchased used, have the paint 
problem.
And yes, all the rigs I've seen, and most accessory products have V- 
tied to common, which is bonded to the chassis.  Which is WHY V- should 
NOT be bonded at the power supply.
