Great stuff for spark plugs. Not only will this help the plugs come out easier in the future it helps in getting the put back in without cross threading.

I have a vehicle where the plugs had not been replaced in a while and they did not thread out very well due to crud in the threads in the engine block. Even after cleaning the threads as best I could the plugs didn't want to thread all that easily with finger tightening. I applied some of this to the spark plug threads and they went right in making it easy to tell if I was cross threading and when I had them all the way threaded so I didn't over tighten them.

If you have a toyota DO NOT BUY!! Toyota cars like the camry and the matrix require a skinner plug and a 9/16ths plug socket buy the sc20hr11.

good stuff, I always wanted a tube of this stuff after buying all those little packets at the auto parts store, definitely worth the price but it will last forever.. you can thin it out a ton. I used it for the surface between my rotors and hubs during a brake job, I hope it will make it easier to get them off next time.

Fit perfect and are very bright. Image has the regular bulb compared to the new led bulb.

I have one of the big 8oz jars of this same anti-seize Permatex 80078 Anti-Seize Lubricant with Brush Top Bottle, 8 oz. that I have used for several years on all manner of projects, but recently I needed to change some spark plugs in a confined space in a boat and I wanted to make sure that I was able to do the job without making any extra mess.

When I was buying the spark plugs I saw these small tubes listed as "also purchased" items and the light went off. This way rather than bringing the big jar with a brush on lid into the boat or trying to pre-lube the plugs and not touch anything on the way in I could sit down in the engine compartment and dab a little on the threads right as I was installing them.

No mess at all, and after use I was able to thread the cap back on and put it back in my jacket pocket so I didn't have to set it down anywhere and risk a mess or worse knocking it into someplace in the bilge that would be a pain to get to it.

Just a dab on the threads will ensure when I need to remove the plugs again from the aluminum head that there wont be a problem. It also works great on a lot of other marine and automotive fasteners and tight fit areas where the use of anti-seize could be tolerated. If you are considering this nickle formula as compared to the copper formulas they consider the copper to be a general purpose and the nickle formulas to have a higher heat tolerance in addition to being able to use on metals that should not be allowed to come into prolonged contact with copper. I prefer to just have this formula on hand.

The one ounce tube is probably enough to last you a very long time if you don't often have a need for it, I do quite a bit of this type of work and I have probably only used half of the 8oz jar I have in the last half a dozen years so for most people this is the one you want to get, but I do like having both as the brush comes in very handy for applying to larger surfaces.

If you are buying this to use on spark plugs also consider a dielectric grease to put in the ends of the boots like this one Permatex 81150 Dielectric Tune-Up Grease, .33 oz Tube or a bigger tube if you do the job more frequently.
