LIQUID ASS:

This stuff is not for the faint-of-heart! Is does NOT smell like sh_t. It smells like ass. Period. Buy a bottle. I am not a shareholder.
My pal actually designed a rig to weld under the frame of his car with a gallon container of L.A. to spray a__holes he might encounter on the road, driving or otherwise.
I'm going to use his design and drive out to the business address of Nate D. Zanders, Auctioneer and circle the block a few times.
