We are steadily making a pretty big pile of fittings and we had planned on sending much of the internal wing fittings out for powder coating. Most of these are not going to be welded parts or at leat are under low stress. I realize powder coating can make it difficult to see cracks in a weld. I thought since we are sending out parts anyway, we have a handful of aluminum parts including the internal flying wire fittings and some small angle pieces that we would like to protect. I know it is possible to powder coat aluminum. Does anyone know of any reason not to?
