Abstract

Polishing pad for use with high-speed mechanical buffers or for use by hand. More specifically, a polishing pad and methods of use for the polishing pad, the polishing pad having a foam pad, and having a cloth, a foam, or both attached to a top surface of the foam pad, with the cloth, the foam, or both covering part of the top surface of the foam pad such that gaps in the coverage allow for the foam pad and either the cloth, the foam, or both to touch a polishing surface at the same time.

Description

FIELD

This application relates generally to polishing pads and methods of use thereof. More specifically it relates to polishing pads having a foam pad with a cloth or a foam or both attached to a top surface of the foam pad, the cloth or the foam or both covering part of the top surface of the foam pad such that gaps in the coverage provided by the cloth or the foam or both allow for the foam pad and either the cloth or the foam or both to touch a polishing surface at the same time.

BACKGROUND

Restoring a surface, such as a paint surface of a car, to a state that is nearly indistinguishable from new has traditionally been a multiple step process requiring an in-depth understanding of paint types, hardnesses, and proper mechanical buffers, polishers, and polishes to complete the process.

Sand paper has been used to remove scratches from paint, but results in markings from the sand paper and leaves a lack of luster.

Polishing a surface with wool can remove some markings from the sand paper, but leaves markings from the wool that leave a surface imperfect, and can lead to damage to the surface if a user is not skilled and properly trained in use. The wool can be used with mechanical buffers that can provide the advantage of speed, but require knowledge for use or can lead to damage to a surface, including in some cases removing a large amount of a paint base coat. There has been a long-felt need in the art for methods of polishing that do not remove the paint base coat.

There has been a long-felt need in the art for simpler, more effective ways of polishing surfaces. Embodiments described herein provide for such needs and provide surprising results.
