Tony, sounds like MT is taking care of the resealing? I hope so. My experience with the MTV-15 was not all that great and it needed to be resealed twice in 300 hrs, the second time because MT neglected to tell the shop that there were updated sized seals when they did it the first time. I also had to fight with MT and it wasn't until I got the CEO of MT in Germany involved that they decided to cover the expense.
My advice to anyone looking for a prop is to steer clear of MT. While MT props have nice performance, it just isn't worth the hassle dealing with them because they do not stand behind their product without you having to fight them.
