Yamaha Trombone Slide Oil

Not really a traditional Tbone oil but emulsion similar in consistency to Slide o Mix. Bought after reading good reviews elsewhere on WWW and can confirm it is really good, particularly on my old Conn that used to feel bit 'gritty' regardless of what else tried. Works great on my main Yamaha Tbone too and lasts for ages without having to re-apply. Don't need to apply a lot. Manns was best price I found as postage included and most others, although slightly cheaper, slapped on a big postage cost.
