Anybody know of a modern replacement for Effasol from Ernest F Fullam? We used it in the materials science department EM lab at RPI in the early 201x's and it was awesome.

It was an aqueous solution that was wiped/sprayed onto the inside of a sputter coater or evaporator bell jar. It would dry to an optically clear, water soluble layer a micron or so thick. After a couple of depositions when the jar started getting too opaque to see through easily, you'd just use a wet paper towel or kimwipe to clean the glass. The sacrificial layer would dissolve and all of the sputtered metal would just come off with almost no scrubbing or effort.
