Some of the more professional trombone players have gone to teflon coating their slides. This allows them to have a slicker slide action without having to lubricate the slides as often. There is a drawback to this process in that if the slide suffers a hard enough impact, it will shatter the coating. I personally haven't had the process done to any of my trombones, as I often have students trying one out, or I use them in a beginning class to help demonstrate technique. I have played on teflon coated slides, and there is a certain quickness about them.
I think a person would have to increase the space between the stockings and the outer slide to make the coating work. I don't know for certain.
