Hi OP, yes you need to re-glaze again and again (unless you're lucky).
I think you should just save your money for a new wallet.
My monogram canvas billfold needs re-glazing as well as my de french wallet, it will be my 2nd time to re-glaze if I do. My last re-glazing was 2011...I rarely used the billfold after that, it was just in its protective cloth (coz I was just at home after giving birth 2012 ) but the glazing started peeling off the sides. I'm just using it now (monthly rotation with my other wallets) even with the loose/hanging glaze
