I originally painted my baffles with high temp paint. It did not hold up well over the years. When i removed the engine for repair recently, i stripped the paint off the baffles and cleaned them up. I think i will install them bare this time. I thought of putting Corrosion X HD on them, but I wonder if they'll be too hot for that to work well (and result in the Corrosion X dripping down on to the engine). The data sheet for Corrosion X says it boils at 400F. Is there any chance of my baffles getting that hot?
