Good anti-seize protection in an easy to use tube that is big enough for most people
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.

Good quality
Affordable, and plenty, you don’t need more than one tube for plugs set.

Good product
These products are great and I use them constantly, BUT The delivery from USPS is horrible. The post man or lady stuffed a cardboard box into the mail box, I couldn't get the box out. I had to use a utility knife to take the box apart inside the mailbox. I have left instructions on delivery and the USPS chooses to ignore them.

Be tidy : Sticks / spreads to everything
Just a heads-up. The product has excellent lube properties for the application. It adheres to anything it touches, and is very durable. But these + qualities require more care and tidiness than most lives. I was sloppy. This stuff spreads like oil paint on a college painter’s hands and is difficult to clean up if it gets where you don’t want it
