Sort of Tinning when i do it - Heat soldering iron to hotest , Apply some solder on a few traces on ur board , rub soldering iron laterally so as to spread the solder along the traces ... the solder will cover all the tracks and in the end you will have a shiny PCB side which will not etch.

Do this before drilling holes.

Vikas has explained the process. Its just covering the copper tracks of the PCB with a thin layer of solder. This protects the PCB tracks from oxidation.
