None of our doors work well with a powder coat finish due to the high temperature to cure the paint.  All doors have body filler on the door edge to fill welds or seams.  The body filler tends to crack and fall out when heated above 300°F.  If a customer powder coats a door CURRIES is not responsible for the effect on the body filler.  The 707 door adhesive and polystyrene core will both be destroyed at these temperatures.  Only the 747 door should be considered for applying a powder coat finish, but CURRIES will not warrant the outcome.
