1. A method of superfinishing a surface, the method comprising: polishing a surface with a single coated abrasive product that includes green, unfired abrasive aggregates and a polymeric resin, wherein the green, unfired abrasive aggregates comprise: diamond abrasive grit particles, anda nanoparticle binder, the nanoparticle binder having a continuous matrix phase in which the diamond grit particles are uniformly distributed,wherein the ratio of green, unfired abrasive aggregates to polymeric resin ranges from about 1.25:1 to about 2.25:1 by weight, andwherein the surface has an initial Ra in the range of about 1.5 micro inches to about 12.5 micro inches prior to polishing and after polishing has an Ra of less than 1.0 micro inch. 2. A method of superfinishing a surface, the method comprising: applying to a surface a single coated abrasive product that includes abrasive aggregates, a polymeric resin, and a crosslinking agent, wherein the abrasive aggregates comprise diamond abrasive grit particles that are uniformly distributed within the abrasive aggregates, wherein the ratio of polymeric resin to crosslinking agent ranges from about 9.5:1 to about 12.5:1 by weight, and the single coated abrasive product is applied to the surface such that the abrasive aggregates are in contact with the surface;moving at least the single coated abrasive product or the surface relative to each other in a first abrading direction, while simultaneously moving at least the coated abrasive product or the surface relative to each other in a second abrading direction not parallel to the first abrading direction while still maintaining contact between the single coated abrasive product and the surface;wherein the surface has an initial Ra in the range of about 1.5 micro inches to about 12.5 micro inches prior to application of the coated abrasive product and after application has an Ra of less than 1.0 micro inch, andwherein the single coated abrasive product is applied to the surface two times or less. 3. The method of claim 1, wherein the single coated abrasive product comprises about 83 wt % to about 28 wt % of the green, unfired abrasive aggregates, based on a total weight of the single coated abrasive product. 4. The method of claim 1, wherein the single coated abrasive product comprises about 16 wt % to about 60 wt % of the polymeric resin, based on a total weight of the single coated abrasive product. 5. The method of claim 1, wherein the single coated abrasive product comprises about 0.5 wt % to about 4.0 wt % of a crosslinking agent, based on a total weight of the single coated abrasive product. 6. The method of claim 1, wherein the single coated abrasive product comprises a crosslinking agent, and a ratio of polymeric resin to crosslinking agent ranges from about 9.5:1 to about 12.5:1 by weight. 7. The method of claim 1, wherein the single coated abrasive product comprises about 0.5 wt % to about 8.0 wt % of a thixotropic agent, based on a total weight of the single coated abrasive product. 8. The method of claim 1, wherein the single coated abrasive product comprises, based on a total weight of the single coated abrasive product: about 16 wt % to about 60 wt % polymeric resin;about 83 wt % to about 28 wt % green, unfired abrasive aggregates;about 0.5 wt % to about 4.0 wt % of crosslinking agent; andabout 0.5 wt % to about 8.0 wt % of thixotropic agent. 9. The method of claim 2, wherein the single coated abrasive product comprises about 83 wt % to about 28 wt % green, unfired abrasive aggregates, based on a total weight of the single coated abrasive product. 10. The method of claim 2, wherein the single coated abrasive product comprises about 16 wt % to about 60 wt % of the polymeric resin, based on a total weight of the single coated abrasive product. 11. The method of claim 2, wherein the single coated abrasive product comprises about 0.5 wt % to about 4.0 wt % of a crosslinking agent, based on a total weight of the single coated abrasive product. 12. The method of claim 2, wherein the single coated abrasive product comprises a crosslinking agent, and a ratio of polymeric resin to crosslinking agent ranges from about 9.5:1 to about 12.5:1 by weight. 13. The method of claim 2, wherein the single coated abrasive product comprises about 0.5 wt % to about 8.0 wt % of a thixotropic agent, based on a total weight of the single coated abrasive product. 14. The method of claim 2, wherein the single coated abrasive product comprises, based on a total weight of the single coated abrasive product: about 16 wt % to about 60 wt % polymeric resin;about 83 wt % to about 28 wt % green, unfired abrasive aggregates;about 0.5 wt % to about 4.0 wt % of crosslinking agent; andabout 0.5 wt % to about 8.0 wt % of thixotropic agent.
