Sliding Roof Lubrication

[Alfie 6]

Hi all, after having some roof repairs carried out, I'm trying to fit the glass back in. Will go in ok, had to shorten the wires by kinking them a tiny amount. They were engaged the locks a bit. What lube can I apply in order to make it slide better. Not that I've used it much, but whilst its out, its the best chance of "greasing" it up slightly?

I use silicone spray if its on the rubbers you need it. Great for electric windows if they begin to slow, or seat belts.
