Abstract: A plastic soft composition is formed of soft base material constantly provided with plasticity, porous fine particles for polishing contained in the base material, and the like, and a polishing process and a coating process are performed to a painted surface and the like using the plastic soft composition. The fine particles for polishing are impregnated with a coating agent (a surface protective agent) added with an activator which is emulsified by contact with water, and the coating agent is held in concave portions formed in the fine particles. Both polishing work and coating work are achieved by sliding the plastic soft composition on a painted surface by a palm pressure of a user.

Abstract: A cured sandwiched article may be used to enhance a portion of a vehicle. In some embodiments, a cured sandwiched article may include a core sandwiched between one or more backing layers and one or more top layers cured to conform to a surface of a vehicle. A cured sandwiched article may be made by steps including shaping a core, positioning the core between one or more backing layers and one or more top layers to form the sandwiched article, and curing the sandwiched article. A cured sandwiched article may be connected to a surface of a vehicle by providing adhesive to a bottom surface of the cured sandwiched article, positioning the cured sandwiched article on a surface of the vehicle, and curing the adhesive. In some embodiments, the cured sandwiched article may include a plurality of fiber-optic fibers.

Abstract: The plastic flexible grinding stone according to the present invention comprises a plastic flexible material having mixed therewith a powder synthetic detergent and an abrasive such as silica sand and calcium carbonate composed of grains from 3 to 50 .mu.m in diameter, and is capable of removing simultaneously minute protrusions and stain from coated surfaces such as of rolling stocks.

Abstract: A clogging phenomenon in the surface layer of the contact face of a soft plastic-and-abrasive composite for polishing painted surfaces, which reduces the efficiency of the polishing work, is alleviated by mixing into the soft plastic backing material of the composite containing abrasive fine particles, non-abrasive globular particles preferably formed out of bubble material. The globular particles are rotatable in the surface layer of the contact face of the soft backing when the composite is in rubbing contact with the surface to be polished. Water or a surfactant may be interposed between the surface to be polished and the composite. The surface to be polished is rubbed with the composite to remove contaminating substances adhering to the surface to be polished.
