An aircraft fuel system includes a fuel cell adapted to contain fuel. A fuel cell receiving assembly has an inner surface adapted to receive the fuel cell. A shaped foam substrate is machined from a foam substrate to fit between the inner surface of the fuel cell receiving assembly and the fuel cell. A polyurea spray coating substantially covers the shaped foam substrate to form a fuel cell cushion. The polyurea spray coating is sprayable onto the shaped foam substrate such that the fuel cell cushion is substantially nonabsorbent of fuel. The fuel cell cushion is interposable between the inner surface of the fuel cell receiving assembly and the fuel cell to cushion the fuel cell from damage.
