A paint and method are divulged for protecting the silver film of mirrors. The paint in its preferred embodiment includes a metal carboxylate which will contribute metal ions, namely stannous octoate for the contribution of stannous(II) ions in an amount of 0.5% or greater by weight. Alternate methods of the invention utilize an additional coating over the paint, such as an acrylic, epoxy or blend thereof which is UV curable. In another form of the paint, copper octoate is utilized in a minimum amount of 0.5% by weight for contribution of copper(II) ions.

The harmful effects exhibited by excess silica (Si.sub.2 O) in electroless metal deposition solutions can be controlled by the use of certain amines. The amines can be prepared in separate solutions or can be incorporated into usual plating solutions to effectively control the effects of excess silica present. The amines can be shown to prevent voiding on glass substrates during silver deposition which often occurs with excess silica of amounts over 0.5 ppm.
