Mike, I haven't read RAH in a few days, and I'm just now catching up,
but your question has drawn a emphatic response from Jim Weir, R.S.
Hoover, AND Cy Galley that you should replace the fabric.

I've been reading this group for a while now, and think I have learned
who knows what they're talking about and who might blow a little smoke
now and then. I would have to say that this is a unique situation.
Dude, if you value your hide, you better ground that plane until the
fabric is replaced no matter how much it cost.

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
