Though I've pulled the seats and cleaned and greased the seat tracks as much as possible, my seats are almost impossible to slide.  I was talking seats with someone at the BBB event and I noticed when they slid the seat out that there was a plastic strip in the track.  Looked like a piece of nylon or some such plastic.  

Does anyone know what i'm talking about, and if so, is it something that acts as a lubricating/wear strip in the track?  

If it is a normal piece, how thick is it?  I can get a piece of 1/16" nylon on amazon and cut a strip to put in there if it's not too thick�

Thanks!
