A corrosion resistant coating system having a first coating and a second coating. The first coating includes a matrix and corrosion resistant particles. The matrix is preferably a matrix material selected from the group consisting of silica, silicone, phosphate, chromate, and combinations thereof. The corrosion resistant particles are uniformly distributed within the matrix and provide the coating a predetermined coefficient of thermal expansion. The particles provide the first coating with corrosion resistance. The second coating is disposed on at least a portion of the first coating. The second coating includes an organic material capable of sufficiently sealing the pores of the first coating to reduce or eliminate infiltration of contaminant material, and is capable of being removed by exposure elevated temperatures.
