Next rule of CA hinges:

Once you have cut them off, either put new hinges along side the old one, or replace them with a different type of hinge. Here's why:

Ca hinges MUST be installed with THIN CA. Thin CA works on a capillary principle, that is, it NEEDS to be used on a porous surface (which is why it sticks so well to skin). But if thin CA has been previously applied to an area, the pores are sealed, so if you get any bond at all, it won't be a good one!
