so you separate the sheets of glass, completely? because that's not what happens in the video! and that is the only way to "remove all the old silicone".
no i take all the beads of and reseal
i have been doing it this way for years
and had no re leaks or no come backs
and i was taught by a man how used to make
fish tanks so i can see we will have to agree
to disagree on this matter
when a tank gets to bad you scrap it
remove to much silicone and you lose
the integrity
