Sven Posted March 13, 2012 Report Share Posted March 13, 2012 We are pulling all the panels and getting ready for our annual. This year we're popping the lid off the engine baffle. The top of the baffle seems to be treated with zinc chromate and the green is looking nice. The underside seems to, at one time, be polished aluminum. There's some corrossion that needs treating. So my question is this. If the bottom seems to be polished aluminum, does this serve a heat-reflective purpose? Should we polish it back up before replacement? Or does this not matter? Could we paint it with an engine enamel to prevent further corrosion? I hope this makes sense as I am typing this well into a generous glass of Maker's 46 (and a couple of Samoa cookies). -Sven Quote Link to comment Share on other sites More sharing options...
Mooneymite Posted March 13, 2012 Report Share Posted March 13, 2012 Are you talking about the top to the "doghouse"? Can you post a picture? Quote Link to comment Share on other sites More sharing options...
DaV8or Posted March 13, 2012 Report Share Posted March 13, 2012 Seems like the last thing you want is heat energy reflecting back at the engine. Maybe paint it black and have it absorb the heat and transmit some out. Just speculating and dna't really know though. Quote Link to comment Share on other sites More sharing options...
Sven Posted March 13, 2012 Author Report Share Posted March 13, 2012 It is the top of the doghouse. Pictures won't happen for a couple of days. It's raining all week and I won't be at the hangar until the weekend. Quote Link to comment Share on other sites More sharing options...
jetdriven Posted March 14, 2012 Report Share Posted March 14, 2012 I say hit it with acid to etch, zinc chromate primer, and paint it white. Quote Link to comment Share on other sites More sharing options...
