Abstract

Abstract This invention is directed to a surface cleaning and coatings applicator tool having a flexible deformable and reformable metal core encapsulated in thin sheets of plastic. These materials of composition give this tool the ability to clean or coat hard to reach surfaces without scratching or marring surfaces adjacent to those being cleaned or coated.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 203 words
A surface preparation and coatings tool comprised of a handle assembly made of a deformable and reformable thin, flat metal core member encapsulated in a thin plastic sheathing material such that said handle retains a deformed shape when bent into said deformed shape, said core member being uniform in cross-section for its entire length; said material completely encapsulates said core member through the application of an adhesive and/or sufficient heat so as to bond or fuse said plastic sheathing material to the core members in a manner that completely protects said core members from the corrosive effects of the chemicals contained in common surface preparation and/or surface coating compounds said plastic sheathing material protecting the surfaces adjacent the surfaces coated from being scratched or abraided by the metal core member; said compounds being absorbed by a resilient, absorbent and/or adsorbent said absorbent member is mountable to and demountable from the handle assembly so as to be reuseable by affixing to said handle assembly a new and/or clean absorbent member; said member is capable of releasing said compounds in a controlled manner; as the compound bearing absorbent member is placed with a sliding motion in contact with the surface to be prepared and/or coated.
