Gas cap threads
 

Any suggestions for the best lube for plastic on plastic threads? My gas cap can be very difficult to get off of the plastic tank, even if I don't tighten it down all the way. The threads just seem to stick. Thx.

I would try some anti seeze compound or a little grease. Just paint the threads with a light coat and you should be good to go. :beerchug:
