Joe Larussa Posted December 22, 2019 Report Posted December 22, 2019 What’s the best way to remove the heat discoloring from your exhaust pipe? Is it even possible? Quote
carusoam Posted December 22, 2019 Report Posted December 22, 2019 Joe, do you have a chromed tail pipe? Did it turn purplish? My plane doesn’t have a shiny enough surface to see a heat affected zone... (HAZ) Got a pic? Best regards, -a- Quote

A serious dose of sand paper and polishing compound will make it look like chrome. It will discolor again fairly soon. Actually, if you polished the tail pipe, it would probably look good for a while. If I were to do it, I would find someone with a powerful glass bead blaster. Remove the pipe and bead blast it till it is a dull grey inside and out (inside is more important to me) Then hit it with 800 grit wet paper till all the sanding marks are even, then spend a few hours of quality time with a buffing wheel with red rouge. Then hit it with Flitz. You will have the nicest pipe on MooneySpace! Quote
MB65E Posted December 22, 2019 Report Posted December 22, 2019 Mine was really nice. Looked like the spinner. After a few years and line service scratching it, looks like anyone else’s spinner. #notworthit. -Matt 1 Quote
Guest Posted December 22, 2019 Report Posted December 22, 2019 Polish, polish and more polish. The stacks on a PT-6 can be kept shiny, so can your tailpipe if you put in the effort. Clarence Quote

ArtVandelay Posted December 23, 2019 Report Posted December 23, 2019 The problem with painting your plane, makes other parts look bad. Like the exhaust. Next you’ll have to armor-all your tires. ;-)Tom 2 Quote
