If the leak is a simple pin hole breach in some minute area of silicone, a surface seal will do.
Sorry to sound like a naysayer here but...
If it is a question of the seams coming apart because the original silicone no longer has tensile strength, this may be another matter.
In the latter case, sealing with a tensile strength supporting silicone, and adding an extra brace (sometimes called a Euro-brace) might go a long way to preventing future problems.
