A gas turbine engine, comprising: an annular shell having an annular shell inner surface and an annular shell outer surface disposed opposite the annular shell inner surface; and a wall panel assembly, having: first and second liner panels (50, 58) operatively connected to the annular shell, the first and second liner panels each having a liner panel inner surface (70, 130) and a liner panel outer surface (72, 132) each extending between a liner panel first end and a liner panel second end (82, 142), wherein the second liner panel is disposed proximate the first liner panel, the first liner panel including a first arm and a second arm, the first arm being disposed proximate the first liner panel first end and extending towards the annular shell inner surface, the first arm being spaced apart from the annular shell inner surface, and the second arm being disposed proximate the first liner panel second end extending towards the annular shell inner surface, the second arm being spaced apart from the annular shell inner surface; a coating disposed on at least one of the first liner panel inner surface and the first liner panel outer surface, the coating having a first overall thickness (t 1) disposed proximate the first liner panel first end and a second overall thickness (t 2) disposed proximate the first liner panel second end, the first overall thickness being different from the second overall thickness; a stud that extends from the first liner panel outer surface through the annular shell inner surface to operatively connect the first liner panel to the annular shell; a plurality of cooling pins that extend from the first liner panel outer surface towards the annular shell inner surface; and a grommet disposed on the first liner panel outer surface, the grommet configured to space the plurality of cooling pins apart from the annular shell and aid in spacing the first arm and the second arm from the shell inner surface. an annular shell having an annular shell inner surface and an annular shell outer surface disposed opposite the annular shell inner surface;
