How long does Electric Paint last?
Electric Paint’s material characteristics do not degrade over time, therefore when you apply Electric Paint, its conductive properties will not change. In-house samples demonstrate that the material can last years if treated properly and kept dry.
So theoretically, Electric Paint used in a project last for years, if it doesn't crack or smudge. If not applied or stored properly, the material may crack over time, however, some cracks may be repairable depending on the application.
Within its container, Electric Paint lasts 1-2 year unopened, and 6 months opened.
