I just got done pulling my car down from ramps in my garage and while I was underneath the car I noticed something strange to me. All over there is this sticky clear goo-gunk....on the oil pan, on the transmission, etc. I tested a small area and it comes off with a little elbow grease, but I am not sure if this stuff should remain or not? The reason I am asking is that it has collected some dirt and crap and it looks YUCK! From a car cleaning standpoint, it was kind of driving me nuts, but I held back from just wiping it all off in case it was some sort of protectant that should remain. Does anyone have any ideas?!? Can this be removed or should it stay?
