Glass?
[edit]Can anyone explain why this works on insulating materials like glass? David Casale 18:37, 18 July 2012 (UTC)
- For David and those interested, glass objects being painted using rotary bell applicators are usually immersed in a conductive coating or are placed on a frame or "buck" fabricated in the shape of the object and made of metal. The paint particles are in the latter case not evenly attracted to the glass surface but rather are evenly attracted to the grounded metal surface behind the glass. The glass just happens to be in the way and the paint particles settle evenly across the surface of the glass. This is additionally how plastics and resins such as vehicle bumpers or rear-view mirror modules are successfully painted this way. AIter Schwede (talk) 01:45, 29 May 2023 (UTC)
