Wasn’t quite sure when it became a normal process but there was a bit on the net to explain it. My take on its use on Austin Healeys is that it wasn’t used.

Electrostatic spray painting was an immediate success as manufacturers quickly perceived the substantial materials savings that could be achieved. With the addition of manufacturing and research operations in Europe and Japan, Ransburg expanded on a global level over the next 20 years. The steady growth was complemented by an increasing reputation for innovative and effective technology.<o:p></o:p></span></p><p style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:15.0pt;margin-left:0in;box-sizing: border-box;Open Sans"orphans: 2;-webkit-text-stroke-width: 0px;word-spacing:0px'><strong><span style='font-size:11.5pt;font-family:""",serif;color:#666666'>Electrostatic coating</span></strong><span style='font-size:11.5pt;font-family:""",serif;color:#666666'> is a manufacturing process that employs <a href="http://en.wikipedia.org/wiki/Charged_particle" title="Charged particle"><span style='color:#568FAC'>charged particles</span></a> to more efficiently paint a workpiece.

I have noticed my BN2 has black factory primer (possible single stage paint that body color was painted over when assembled- much like eletro coat primer that repo parts have on them). All later cars (BN4 on) that I have had experience with had red oxide primer used from the factory. Does anyone know was there a switch point? Were all 100's primered black? Were all cars eletro coated, and later cars primed with red oxide additionally? Was elctro coating even a thing back then? Just curious.<o:p></o:p></p></div><div><p class=MsoNormal>TY.
