Peelable Resist
 
Best described as a thick normally blue plastic covering which is resistant to soldering processes. It's designed to tent over component or mounting holes and prevent them from filling with solder during wave soldering. Another use is as an alternative to masking tape in order to protect edge connectors. The ink in the tin before use closely resembles window putty, and also requires a special silk screen covered with a very course mesh. Once applied it only takes an odd minute of baking to turn it into its solid dry form.

Please note that on conventional non PTH circuits by either taking a small section out of a pad or creating a solder relief area using ink, it is possible to reduce the number of holes that fill with solder. The removed or covered section optimum shape is best described as a Packman mouth which is almost closed.
