had a question recently that may be of interest. The question was: “How do I lubricate my window slides and door lock hardware in my antique cars?”
I use Fluidfilm to lubricate window regulators and the latch on the inside of the door. I undercoat my cars with Fluidfilm in the fall, and keep a five gallon pail in the garage for little projects. I keep a paint brush in the bucket, and use it to apply. Fluidfilm works well as a lubricant, does not wash off, and does not attract dirt.
