I find all this reg seat talk very odd..
For one reason. I have very rarely had a problem with a first hot shot or a bad reg seat. I have used a mag for about 4 years and played almost every week. after every session I took my mag halves apart, clearned the arear with q-tips and the like, oiled the reg seat and put them back together. Now I am being told that I should seal the two halves and forget about it. My point is that if you are careful and dilligent I think you can prolong seat life by a careful cleaning and oiling like I described above. I may be drunk but in the 4 years that I have shot I mag I have replaced my reg seat perhaps 5 times.
Is this odd, what is the service life of a reg seat???

PS> I will say this and perhaps this is the key. In all the time in using my mag I fill my own SCUBA tanks and the SCUBA fill station owner prides himself on clean filters and clean fills. Perhaps I owe more of this too slean air rather than clean reg seats...
