The thrombin and fibrinogen are freeze-dried and packaged in vials that must be warmed before use. The two ingredients are then dissolved in separate amounts of water.
Fibrin is not normally present in the bloodstream because it is a part of a blood clot. To have circulating fibrin would be to have circulating blood clots, which is a medical emergency. Within the plasma, however, is the precursor to fibrin - fibrinogen. When this is activated, such as by signalling molecules released by damaged cells lining a blood vessel, fibrinogen is cut into fibrin at that location to create a clot and stop the bleeding.
No, fibrin is not a white blood cell. Fibrin is a protein that plays a key role in the blood clotting process, helping to form a mesh-like structure to stop bleeding. White blood cells, on the other hand, are part of the immune system and play a role in fighting infections and diseases.
If those options were not part of the deal, then tell the dealer that you will not pay for them. If you signed for those options, unless you can persuade the dealer to leave them off, you are stuck. Sealants are a total rip off.
Yes. Anaerobic sealants cure without air (such as two part epoxies, etc).
In a braking system, if the part has failed or is leaking, then it has to be replaced. There are no sealants used on a hydraulic braking system.

Primary hemostasis is the overall sequence of events that leads to the formation of a platelet plug, while Secondary hemostasis is the signal transduction pathway that leads to the formation of fibrin. Secondary Hemostasis is always a part of Primary hemostasis, but involves many clotting factors and other signaling molecules that are specific to the formation of fibrin
