| Re: Ultra-Pure Oils I just got my Ultra-Pure Oil the other day, and it's amazing! I'm using this oil in my 1968 Getzen Eterna Severinsen model, and it's made the valves even more fast, and this trumpet plays even better than ever! I used to use Blue Juice, and that is also very good oil, but I noticed an immediate improvement after applying some Ultra-Pure Oil. |
