Best way to apply pvp (or a viscous solution) to coverslip - Microscopy Technique (Oct/30/2010 )

Hello,
I am trying to apply a uniform coat of PVP (polyvinylpyrrolidone) to glass coverslips. Does anyone have a protocol for this?

Thanks.

For things like gelatine or collagen, this is usually done by adding an amount to the coverslip/slide such that it coats the whole surface, then allowing it to dry.
