ABSTRACT:
The present process for the production of sparkplugs provides coated sparkplugs that are resistant to carbonization or lead fouling of the central ceramic insulator. A liquid metal carboxylate composition is applied to the insulator of the sparkplug and subjected to heat treatment at a temperature preferably above 400.degree. C. to form a durable metal oxide layer on the insulator.
