I have seen several. Stainless wont have this problem.
Time vs. time basis, you nor I can say which will last longer because there is no evidence, only theory. You and I could go back and forth and contradict each other in theory on why one would fail first or the other last longer. Only time can tell, my friend, but I'm not buying the idea that we're gonna see the SS DPs falling apart in 6 months.
