1. An applicator for a fluid coating material comprising:
- a coating pad for metering said coating material onto a surface;
a support for said coating pad;
a passageway within said support for conducting said coating material to said coating pad;
said coating pad being an open pore foam having an average number of pores from 12 to 25 per linear centimeter with the average pore size being from 0.4 to 2 microns and with a pad rigidity such that a 400 gm/cm2 causes a compression of less than 20%

Abstract
An applicator for coating materials, such as shoe polish, is made with a relatively rigid open cell foam coating pad. The foam has an average of from 12 to 25 pores per linear centimeter with an average pore size being from 0.4 to 2 microns. The pad rigidity can be provided by a hard material per se or by having a flexible porous foam material compressed from its original volume to from 1/10th to 1/20th its original volume. The coating pad has less than a 20% compression when subjected to a 400 gm/cm2 pressure. The coating pad can be used with a pigmented coating material or polish with an average particle size of from 0.4 to 1 micron.
