> 3 dayI have a lot of titanium on my mid school ride from my former Factory Crupi days. Titanium on titanium is instant gall (If you didn’t know) and titanium on chromoly or chromoly on aluminum is a galvanic corrosion nightmare. This stuff is a life saver! IMO Park Tool is the industry reference.

> 3 dayI purchased this product to use on new Shimano SPD-SL pedals I was putting on my road bike. Got the idea from the Park Tool YouTube video on how to change bike pedals. Only advice I can offer is to use it sparingly. I thought I was being stingy with the amount I put on the threads and noticed that upon tightening the excess grease ended up all over my pedal cranks. Trying to clean it up is very hard and messy so apply as little as possible to get the job done.

> 3 dayI purchased this thinking it had 4oz of compound and it’s mostly air inside the tube? Truly misleading. There’s actually just about 1oz of stuff inside. Update: I wrote parktool complaining about the quantity and they wrote back saying the tube didn’t fill up all the way and it’s defective. They asked me to return it to Amazon for a replacement.

Greater than one weekWorks great for steel bolts in alloy parts. Would be nice if a smaller tube was available. A little is all you need.
