I know that you are supposed to use a "special" paste for this, but regardless of that, exactly what is it you are supposed to lube. The sunroof on my '87TD opens slowly sometimes and other times it moves along quickly. Does anyone know where the lube is supposed to go and can I use something else like white lithium grease?
