Good old red threadlock
Purchased this after doing some research into red threadlock. Back in the days (of 1995 it would seem), cars (maybe just mine) called for red threadlock. In the service manual of my 1995 E34 BMW they didnt call for a 263 loctite threadlocker but instead just called for red threadlock. Now with some considerable digging and references across forums and Loctites own data, I was able to determine that 263 is the closest modern version. 263 is also indeed red. So if you're here for that, then I hope my review acts as a confirmation. With that said, the threadlocker performs as it should. The suspension/drivetrain component that I used this on (following the factory service manual) had yet to come undone and fail. And it had been roughly 10k km after the repair so I would say it's held up well. I've yet to need this in any other applications at the moment but if it's been trusted on a crucial component of a close to 30 year old car and then performed according after use then I'd say it's trusted in my books. So definitely recommend 263 for all 263-related and red loctite-related applications.

It locks the threads like it should.
It locks the threads like it should. It seems to be very strong and takes a LOT to get the fasteners loose again. I would buy it again.
