A surface treating article including a quick release fastener. The fastener includes a first end opposite the article, a second end adjacent the article, a tapered portion increasing in cross sectional area in the direction from the first end to the second end, a groove located between the tapered portion and the second end, and a mating portion having a non-circular cross section. Preferably, the mating portion has a hexagonal cross section. Also disclosed is a backup pad for use with the surface treating article. The backup pad includes an opening having a cross sectional area that corresponds to the cross-sectional area of the mating portion of the fastener. The backup pad also includes an o-ring in the opening to engage the groove in the fastener.
