Various forms of spark plug thread lube anti-seize have been around for years, but many experience the same application problem: they ball up and are very difficult to spread evenly across the threads. Tempest T556 formulated spark plug thread lube anti-seize.
Tempest T556 comes packaged with a brush that applies the lubricant to the threads with a smooth even flow, doesn't drip, and more importantly, won't inadvertently run down on the firing end of the spark plug potentially causing an environment conducive to fouling or even pre-ignition. It stays where you put it and covers like a blanket on the first pass!
Works fine as a lubricant however, it will gum up in the bottle and evaporate if stored. This leaves you with a pasty substance that is useless.
