Slide Prep.

There are lots of opinions about which is the best slide lubricant and about as many on how to apply it. I use Trombontine and only apply a little bit to the inner slide stock and then work the outer slide over to distribute it. If the slide doesn't seem super fast at that point, I'll wipe off the inner slide and spray with water. Before I do that though, I'll clean the inner and outer slide well, using a cleaning rod with a cloth worked back and forth inside the outer slide until warm for each tube. I've tried the Yamaha stuff and it seems to just slide off the metal like snot and did use Superslick for a long time before that, but found Trombotine to be more durable and slicker.
