My trunk latch mechanism stopped latching closed last winter in cold temperatures (below -5C or so). It would latch properly after heating it up with a blow drier. I sprayed some lube into it (I believe WD40 first, then some white lithium grease). Eventually it started working properly, but this may have been partly due to the warming weather. So far this winter it has worked down to -20C, until today when it got stuck in more mild conditions.
Anyway, I'd like to know what the best lube would be to try, before I replace the latch with a new one. I'd like to use something that is good in low temperatures (down to -35C) and available in a spray.
