That's the trick!

I give the other reviewers right: the porcelain glue stinks beastly, but only until the solvent is evaporated and the might take an hour. Otherwise, it works flawlessly!
The trick is, the excess glue off easily allow !!! After about 12-15 hours of drying time: you can easily replace it with a fingernail in one place and easily peel off from there with your fingers! Residue-free! Looks properly !!!
I made the rookie mistake at the first bonding and have the trespassing Kleber tried frantically with cloth and wipe your fingers. So I had the fingers fully (not going really well off) and distributes the adhesive on the wafer-thin porcelain - also is not really well off, you have to scratch with your fingernails or a knife. So that's quite at ease the excess glue off leave and remove after some time simply.
Highly recommended!
