Versachem 15309 Dielectric Spark Plug Boot Grease - 7 Grams

product seems to be good and as expected

Does the intended job.

Good size, good protection, used for my ignition coil pack boot, good value.

Does what it's intended to do good value for the cost

Dielectric grease is the electrician's gold standard for retarding corrosion in electronic or electrical situations. Enter this little tube. Ground faults are endemic in a marine environment, and even on merely ("marine" means salt water to sailors and mariners) lakes. So, every one of the 24 ground straps on the buss in my ski/wake boat will be removed, polished with crocus (or emery; choose your preference of type) cloth on the nuts and bolts and particularly on the ring connectors and reinstalled. Because our boat is a morass of irregular performance among instruments and lights. Based on my experience, and the intermittent successful use of these, I'm betting on wonky grounds... Cleanup (see the color difference from installed/base-cleaned on the right and not-yet connectors to the left) and prevention should identify any actually 'bad' units, and cause a repetition of the wonky behavior to be a thing of the past.

I use a very light coating of this on the threads of all my outside light bulbs. It prevents corrosion and seizing, and makes the removal of bulbs easier and safer (no breaking off in your hand). A little goes a long, long way, and it will save you some aggravation when it's time to re-bulb.

Worked as it should

I like the way it worked 4 me. Used on some new plug wires. Works great.

Its good but as most have said the quality is too little. Its a tiny tube very different from the picture once seen in real.
