1. A fan blade, comprising: an airfoil section of a fan blade for a gas turbine engine, the fan blade including a free end; anda sprayed on abrasive coating bonded to the free end, the abrasive coating comprising a polymer matrix and an abrasive filler, the abrasive filler between about 50%-75% by volume of the abrasive coating wherein the filler comprises hollow glass microspheres. 2. The component as recited in claim 1, wherein the polymer matrix provides about 3%-10% volume of the abrasive coating once cured. 3. The fan blade as recited in claim 1, wherein the abrasive filler is zirconia. 4. The fan blade as recited in claim 1, wherein the abrasive filler has an average particle size of 220 mesh. 5. The fan blade as recited in claim 1, wherein the polymer matrix outgases during elevated temperature curing. 6. The fan blade as recited in claim 1, wherein the polymer matrix maintains porosity between grit particles of the abrasive filler. 7. The fan blade as recited in claim 1, wherein the polymer matrix includes at least one of an epoxy, polyimide, polyurethane, cyanoacrylate, acrylic, and combinations thereof. 8. The fan blade as recited in claim 7, wherein the abrasive filler includes at least one of zirconia, alumina, silica, cubic boron nitride (CBN), and combinations thereof. 9. The fan blade as recited in claim 1, wherein the abrasive filler is of a volume of the abrasive coating such that capillary action facilitates retention of the polymer matrix between particles of the abrasive filler. 10. The fan blade as recited in claim 9, wherein the free end comprises a distal end and an extension around a sides of said airfoil section. 11. The fan blade as recited in claim 1, wherein capillary action facilitates retention of the polymer matrix between particles of the abrasive filler. 12. The fan blade as recited in claim 1, wherein the fan blade is a polymer composite upon which the abrasive coating is sprayed. 13. The fan blade as recited in claim 1, wherein the fan blade is a polymer coated aluminum upon which the abrasive coating is sprayed. 14. The fan blade as recited in claim 1, wherein the free end comprises a distal end. 15. The fan blade as recited in claim 1, wherein the polymer matrix is not utilized to carry the abrasive filler during spraying. 16. A fan blade, comprising: an airfoil section of a fan blade for a gas turbine engine, the fan blade including a free end; anda sprayed on abrasive coating bonded to the free end, the abrasive coating comprising a polymer matrix and an abrasive filler, the abrasive filler between about 50%-75% by volume of the abrasive coating, the polymer matrix comprises about 3%-10% of the volume of the abrasive coating when cured wherein the filler comprises hollow glass microspheres. 17. The fan blade as recited in claim 16, wherein the abrasive filler is zirconia. 18. The fan blade as recited in claim 17, wherein the abrasive filler has an average particle size of 220 mesh. 19. The fan blade as recited in claim 16, wherein the polymer matrix includes at least one of an epoxy, polyimide, polyurethane, cyanoacrylate, acrylic, and combinations thereof. 20. The fan blade as recited in claim 19, wherein the abrasive filler includes at least one of zirconia, alumina, silica, cubic boron nitride (CBN), and combinations thereof.
