We have used this at school, where we build a Formula-style racecar for
competiton. ON an older car, the bore for the front wheel bearing was very
loose (similar config. to rabbit front bearings but 2 sealed ones). It was
loctite and it was green. I can get the part number tomorrow and compare it
to what dennis used. It saved us a lot of resources and time to keep the
car running. I do know that the actual stuff we use is labeled under
Volvo... apparently older team members thought it could only be obtained
through them, but we have a new bottle from loctite now as well.
