REFLECTOR: Repairs exhaust Coting

[Mark Magee]

In reviewing this you will see lots of folks coating the external surfaces
with ceramics, but this is predominantly for cosmetic effect and corrosion
reduction, and will be OK as long as the internal surface is coated. The
internal ceramic coating will be keeping the heat flowing toward the cool
end and from stagnating in the metal.
