Re: updates with pics
As far as I know- silicone should NEVER be used below the waterline.
I like to use a product by 3M(?) - 101(?)
I believe it is called.
Gives excellent adhesion & never dries out.
Fittings can be removed in the future w/o any damage to the fitting or glass - unlike 5200.
It is a rare occasion that I would use the 5200.
