With all of the lube recipes and folks over the many years trying everything under the sun, how do you know that nobody has tried snot? I betcha someone has given it a try. I have no idea how it would work :idunno: but even if it turned out to be excellent stuff, where would you get a reliable source. No problem for allergy sufferers or during cold season but if you are healthy, you are screwed. :haha: Even if you had a good source, you would still have to pick out the boogers.
