Combustion Turbine Exhaust corrosion

The exhaust stacks on my combustion turbines are not lined, i.e. bare steel. Every time we start a unit, it rains rust flakes. A vendor has offered to "flame spray an aluminum coating" on the inside of the exhaust stack.

Does anyone have experiense with corrosion in this area? Does anyone have experience with aluminum flame sprayed coatings on the inside of a gas turbine exhaust stack?

Thanks in advance.
