I’m building four BREX plug door reefers from Sunshine kits, and
they all had Apex steel running boards. The kits includes etched stainless
steel running boards. My question is, aside from the end overhang, which is
painted mineral red, should I leave the rest unpainted or paint it aluminum
color to match the roof? The hatch cover latches are also etched stainless
steel parts. Same question, to paint or not to paint?
