Loctite 555336
As I stand on the threshold of a familiar path, where the familiar grip of seizure often ceases the smooth flow of life's little mechanical functions, an 8-ounce copper soldier stands guard in my toolkit: the Loctite 555336 Copper Anti-Seize Lubricant Brush Top, found within the myriad possibilities of Amazon. This humble lubricant, much like the coppery sun rising in the east, promises a new day free of the friction and resistance that has so often halted progress in my workshop. Its coppery glow speaks not just of anti-seize but of freedom and fluidity, of uninterrupted rhythm and ceaseless motion. It carries the promise of endless possibilities, a golden path where seizure and friction have no dominion. Yet, in its prowess lurks a peculiar tenacity, an unrelenting permanence. Beware its silken touch, for it adheres with a steadfastness reminiscent of Frost’s “Road Less Travelled.” It marks its path with a lingering copper glow, a testament to its presence and an assurance of its commitment against the ceaseless foe of seizure. A commitment that, once made, is difficult to revoke. Each stroke of its brush is a poetic verse against the wear and tear of time and use. A sonnet of protection, a haiku of endurance, a ballad of resilience. Its lustrous copper hue, not unlike autumn’s foliage under the glow of the setting sun, enhances not just the aesthetics but the lifetime of my tools and fixtures. Yet, it is not just the glow or the permanence of the Loctite 555336 that marks its triumph. Its true victory lies in the ease it brings, the simplicity it offers in the face of otherwise arduous tasks. It transforms what was once a struggle into a task as effortless as the flow of a Frostian poem, as easy as choosing the path less travelled by. Thus, as I behold the coppery glow of the Loctite 555336, I am reminded of the words of Frost: "I took the one less travelled by, and that has made all the difference." This lubricant, in its coppery radiance, has certainly taken the path less travelled by in the world of anti-seize lubricants, offering not just functionality but a hint of permanence and an assurance of quality, thereby making all the difference in my workshop endeavors.

A Must-Have Around the Shop
A must have for working on any farm equipment. Absolutely prevents rust from seizing nuts and bolts. Just don't get it on any clothes you don't want stained, as it will not come out. Good value, works well and easy to apply

Loctite, the best in the business.
The bottle is very very full. It comes sealed with a nice brush attached to the lid. It comes in a sealed clear bag in that bag is inside another bag and then that bag inside the shipping bag. I have had a bottle of this for about 25 years now so I have a feeling this will be the last bottle I will ever need. I love all my Loctite brand chemicals and material.

Good product from a trusted company
It’s difficult to review a product that’s used to prevent seizing of parts after just using it. I’ve used aluminum anti-seize for years, the Copper compound is regarded as higher quality. I’m giving 5 stars based on the consistency of the product, price and previous use of products from this company.

Product Good But!!!
I love the product but It was used. Bottle was half full. It must have been a return and they used some of it. I urgently needed it so I just had to keep it.

BUY THIS STUFF!
I have, since the dawn of time, had a bottle of the Permatex version of this and it finally gave up (got weird and hard-ish). Looking at the msd sheets for that and also for this one, i saw this stuff had way more of a percentage of copper and of graphite than the Permatex, and far less ground minerals. Limestone for some odd reason! About the same price too. It brushes on well, coats metal nicely, and hangs in there as you brush it THIN. If stuff like this doesn't last you twenty years or more then you're using too much. This goes for brake jobs too. Washes away from the forbidden places instantly with a blast of brake cleaner. Doesn't stink up your hands. And don't wear a nice unstained shirt. Copper and graphite, remember? You've been warned.
