I used Hetmans for the first 3 years I had my horn. I've since switched to Pro Oil and haven't had any problems with the rubber staying in tact. After a playing my horn for a few months, I did notice that the "silent valve system" (rubber pads) weren't staying in place, so I got our school's repairman to glue them back in. I'm sure DEG would be able to send some new ones though.
