I loathe Stan's. I swear I clean the rim 60 times, stretch it till my fingers almost bleed, and the shit still leaks half the time. No way it should be this hard.
I used gorilla tape once and it absolutely does not leak, but it's thick enough to affect the rim bed and it leaves quite a bit of residue.
Broke a spoke and two reapplications of stans later I'm ready to stab myself.
They are 35i rims so I think maybe the width of the tape is an issue, I also think I should be using narrower tape, like 25, whatever covers the holes...
