I don't have a brand recommendation. I just found something at the parts store that was labelled as being High Temperature Silicone Brake Grease. It was almost clear (slightly yellowish) and came in a plastic tube.

PS I don'tthink it has to be "High Temperature" but that was what was printed on the tube I bought)

For regular rubber you would use a spray bottle with a dilution of 1/4 gram or somthing like that of dry graphite to the whole bottle dilutted with water and alcahol. when the water and booze drys away it leaves the dry lubticant (graphite) in place. For the kit we are talking about way back when Motorsport used tell you to wrap them in Teflon tape. I don't have a radio in the beast And the only noise I hear is the wrong offset rims rubbing the fenders. Back in the day the teflon tape was an old school trick to use when harder urethan bushings came out. :devious:
