Last year my dad, my brother and me finnaly fixed up an old trailer we had, we derusted it and painted all that was not easy but wasn't nasty. But the bearings...oh my gosh...NASTY. We put new greese and new bearings for the trailer's wheels. We had to take the cap off and clean out all the old greese that had been in there well over 20 years. It looked like old peanut butter it was so gross, and if you got it on your hands you couldn't just wipe it off, you had to scrub hard. Not to mention the smell, you definalty would not want to eat after doing somthing like that.
