I guess the main reason some are against using copper slip, or any form of conductive grease is encase it might get on the insulator, and track the spark to ground, but to be honest, you'd have to be quite messy, and use an extreme amount to tempt this.

I use copper grease for its conductive characteristics but sometimes I get headwind...
never got a spark plug issue, but no idea if lubricant is necessary either, I just do it...
any idea why opinions do vary a lot on this subject ?
