1968 m20f.  Pretty good blue stain under pilots wing.  Got some good info from the vintage Mooney fb group- but was hoping for some more in depth conversation on figuring out a “theology” of when to go for a full reseal or bladders vs a patch?    how have you all made that decision? I’ve only owned it since April, does one patch for a hoped one off that will hold, then see if it’s just going to be constant chasing? Until one gets to know the bird?   I’m nice they start they don’t stop?  d
