Leak from rear view mirror housing?

I saw a one inch streak coming from the plastic rear view mirror housing on the windshield. Upon touching it i found it to be an oil like substance. Real thin, like wd 40 or something? Maybe armor all? I've never used it but only had the vehicle for two weeks.

Mine did it once right after I got it and hasn't since, so I have never bothered with it. Ironically the loaner they gave me last week had the same issue and I pointed it out when i returned it.

I am worried it only does it in the heat and when summer comes it will be leaking again.
