It was initially sent out to lubricate the fusers on the C452 I think. I don't have any C452s so I use it for other things. I had a car window that was very slow going up and down, so, I squirted some Drysurf between the glass and frame and it worked great. Window now goes up and down smoothly. That was in the summer and still working. Seems to be good stuff.
