Have you ever seen a weight weenie who likes 21 pound full suspension mountain bikes or 11 pound road bikes, install titanium bolts into an aluminum or carbon fiber frame to save 30 grams on the overall weight of the bike? Or even worse, install a titanium bolt into a titanium frame ? (not recommended even with anti-seize compound) I have, and unfortunately I have also seen the damage done when someone tries to forcefully extract the same seized titanium nut or bolt a year later, which then has to be drilled out or in some cases can even ruin the frame. That is where anti-seize compound comes in. And Park Tools formulation is just as good if not better than any generic compound you buy at an auto store. I have no idea what the exact elements are in this Park Tools lube but I would not be surprised if it was partially Moly-50 with some zinc added for best protection with aluminum and titanium. (which also would work equally well with carbon fiber). At any rate, this lube works well. Very nice to have for bottom brackets on my titanium hardtail and for bolt hardware. I have been using this lube for multiple rebuilds over the last 15 years roughly and this has saved my butt from galled, corroded and seized components on more than one occasion. In my book, that makes it five stars!

Awesome Compound, it really does work. I will say it’s a lot for the price but since it’s made in America you get what you pay for. It will last me a long time, as long as you use it in small amounts, it wasn’t just perfect for my bottom bracket, but Threaded surfaces like limit screws, axles, cone nuts, axle nuts, threaded spacers, etc. I’ve used this on Limit screws, my Bottom Bracket, any place with a machined threaded surface, hole etc. In fact on my bottom bracket shell of my frame was threaded, I did put ASC-1 grease on the threads inside the shell before installing the Bottom Bracket. The biggest problem I have had is the stripping of the threads, which is my biggest problem, so I started using it on screws on my derailleurs including my freewheel, and anything and everything with a threaded surface going into metal parts. This stuff really is awesome, and Park Tool is a brand and company I trust completely they really do know what they’re doing. My only Recommendation to Park Tool is to put this in a tub like they have with PPL-1. Otherwise if you go through a lot of this you have to be prepared to spend a lot. Otherwise, I highly recommend it!

You apply this on joints and threads that are not meant to move against each other, so that you can take them apart in the future.If you’re like me, and was clueless about what’s the difference between anti seize compound and polylube, watch the video by Park Tools showing the difference. If you’re packing ball bearings, use polylube, not anti seize compound. However, you can use polylube to grease threads. So why get anti seize? They are supposed to last longer, and also prevent galvanic corrosion between dissimilar materials. May not matter much with bicycles, especially for parts that get removed and grease reapplied regularly. But I had a tough time removing my old pedals, and decided to get this as it doesn’t cost much and I expect to need it somewhat frequently.

Good stuff – an absolute “must have” for any serious do-it-yourself bike owner. But don’t let the oversized tube fool you. As the description says, it’s 4 oz of product… but it comes in a 12 oz sized tube. A tube will still last years, but getting all the product out of it might be problematic. Great product – dumb packaging. That being said, it’s a great product that should be in every bike owners tool box.
