1. An apparatus comprising: a shaping portion having a cavity configured to receive a fastener system and receive a sealant;a centering portion having a channel configured to position the shaping portion in a position around the fastener system when the fastener system is received in the cavity; and
1. An apparatus comprising: a shaping portion having a cavity configured to receive a fastener system and receive a sealant;a centering portion having a channel configured to position the shaping portion in a position around the fastener system when the fastener system is received in the cavity; anda support system comprising a number of support elements configured to secure the shaping portion and the centering portion to a surface of an object in which the fastener system is installed when receiving the fastener system, applying a layer of sealant to the fastener system, and retracting from the fastener system;wherein the sealant received in the cavity of the shaping portion forms the layer of sealant over the fastener system within the cavity; andwherein the shaping portion, the centering portion, and the support system form at least one of a sealant applicator or an automatic sealant applicator, and a thickness of the layer of sealant stays substantially the same during all phases of application and removal of the sealant applicator or the automatic sealant applicator. 2. The apparatus of claim 1, wherein the centering portion is concentrically located within the cavity of the shaping portion and is further configured to moveably retract within the cavity of the shaping portion during delivery of the sealant. 3. The apparatus of claim 2, wherein the support system is physically associated with the shaping portion and the centering portion and is configured to maintain a position of the apparatus relative to fastener system when the centering portion and the shaping portion retract to form the layer of sealant over the fastener system. 4. The apparatus of claim 1, wherein the support system remains in place during removal of the layer of sealant and the fastener system from the cavity of the shaping portion so that removal of the layer of sealant and the fastener system from the cavity of the shaping portion occurs without substantially altering a shape, the thickness, or a size of the layer of sealant. 5. The apparatus of claim 2, wherein the centering portion is configured to move within the cavity of the shaping portion between an extended position and a retracted position; to position the shaping portion in the position around the fastener system when the centering portion is in the extended position; and to deliver the sealant into the cavity when the centering portion is moved into the retracted position. 6. The apparatus of claim 5, wherein the centering portion is configured to receive the fastener system in the channel when in the extended position within the cavity of the shaping portion and move the fastener system out of the channel when in the retracted position within the cavity of the shaping portion. 7. The apparatus of claim 6, wherein the centering portion is configured to move along an axis extending centrally through the fastener system when moving within the cavity of the shaping portion between the extended position and the retracted position. 8. The apparatus of claim 5, wherein the centering portion comprises: an interlocking base section configured to engage with an inner surface in the cavity of the shaping portion when the centering portion is in the retracted position. 9. The apparatus of claim 5, wherein the cavity in the shaping portion is configured to cause the sealant to form the layer of sealant having a thickness corresponding to the retracted position of the centering portion. 10. The apparatus of claim 1, wherein the shaping portion comprises a plurality of interlocking sections. 11. The apparatus of claim 10, wherein the plurality of interlocking sections is configured to seal the shaping portion against an uneven surface around the fastener system. 12. The apparatus of claim 11, wherein each of the plurality of interlocking sections is configured to move independently of others of the plurality of interlocking sections. 13. The apparatus of claim 1, wherein the support system is configured to maintain a radial position of the centering portion relative to the fastener system as the centering portion moves between an extended position and a retracted position, and to maintain the radial position of the shaping portion as the shaping portion is removed from the fastener system. 14. The apparatus of claim 1, wherein the support system is selected from at least one of a vacuum sealing device, a magnet clamping system, a lock, a clip, a track, a mechanical relative position location device, or a robotic arm. 15. An apparatus comprising: a shaping portion having a cavity and a number of interlocking sections configured to move independently of other interlocking sections, in which the shaping portion is configured to: receive a fastener system in the cavity; andreceive a sealant within the cavity to form a layer of sealant over the fastener system;a centering portion moveably located within the cavity of the shaping portion and having a channel and an interlocking base section, in which the centering portion is configured to: position the shaping portion in a position around the fastener system when the fastener system is received in the cavity;move between an extended position and a retracted position such that the shaping portion is in the position around the fastener system when the centering portion is in the extended position, in which the centering portion moves along an axis extending centrally through the fastener system when moving between the extended position and the retracted position;receive the fastener system in the channel when in the extended position and move the fastener system out of the channel when in the retracted position, in which the interlocking base section is configured to engage with an inner surface in the cavity of the shaping portion when the centering portion is in the retracted position; anddeliver the sealant into the cavity of the shaping portion when the centering portion is in the retracted position to form the layer of sealant with a thickness corresponding to the retracted position of the centering portion; anda support system physically associated with the shaping portion and the centering portion selected from at least one of a vacuum sealing device, a magnet clamping system, a lock, a clip, a track, a mechanical relative position location device, or a robotic arm, the support system comprising a number of support elements configured to secure the number of support elements to a surface of an object in which the fastener system is installed, in which the support system is configured to: hold the apparatus in the position when the centering portion and the shaping portion retract to form the layer of sealant over the fastener system;maintain the position of the centering portion as the centering portion moves between the extended position and the retracted position; andmaintain the position of the shaping portion as the shaping portion is removed from the fastener system, in which the shaping portion, the centering portion, and the support system form one of a sealant applicator or an automatic sealant applicatorwherein the number of support elements are configured to secure the shaping portion and the centering portion to the surface of the object in which the fastener system is installed when receiving the fastener system, applying the layer of sealant to the fastener system, and retracting from the fastener system; andwherein the shaping portion, the centering portion, and the support system form at least one of the sealant applicator or the automatic sealant applicator, and wherein the thickness of the layer of sealant stays substantially the same during all phases of application and removal of the sealant applicator or the automatic sealant applicator.
