I do not have the rubber door gasket on my LIVP.
Initially, after a great ground test, I had a lot of door seal leaks at altitude that were cauused by a larger gap than tolerable and subsequent outward flex of the inflated seal. Plus the lower edge of the door frame was angled outward more that the seal tolerated, allowing a more vigorous slippage and leak. I have built up the inner door frame, especially around the complex corner curves, and flattened the lower edge so they rubber door seal does not flex outward after a bit of air time and positive cabin pressure. This solved the door seal issue.

Hi Fred,
Dennis Pratt (s/n 54) has been flying for over 10 years now and has almost 1300 hours on his airframe and has never installed the strip you are talking about. He routinely flies in the flight levels. Of course, the door is pretty evenly spaced all the way around, so the seal doesn't really have to "stretch out" to seal the gap.
A lot of things I have done to mine were dictated by his real-life experiences. I don't plan to put the strip on mine in the beginning either - I may have to later.
