Polishing airplane exhaust. Or at least trying to.

Listen, I had no idea how hard this was going to be. I tried several different processes in this video and a couple more after the camera was off.
come along as I work through this job. it honestly had me stumped. but through a little trial and error I was able to achieve a finish that the customer was happy with.
The brightner is from purple power.
all other polishing products are from www.goshineon.com

Love the content. Your doing a great job.

[@DontCallMeGarage]

a white or light grey scotch brite blending wheel would have been a good start for that stainless.

I would like to see the PPE you use in your shope while you are working.

[@tomv7552]

There was a big change after you sprayed it with glass cleaner

[@summershine_7702]

Yeah the brightener definitely broke down that film on the little pipes.

[@rubenparedesjr3412]

Got it.

[@Roadhouseee]

I think it’s 625 inco. I think the welds would look much better if it was stainless.

[@summershine_7702]

Thank you Dalton. Yeah definitely inco. It was wicked hard.

@@summershine_7702 I'm going to hazard a guess that the white coating on the big exhausts is ceramic coating to keep the heat inside the exhaust, probably Zircotec. It would eat up sand paper.

@@summershine_7702 I wonder if a lot of the problem is lead staining of the exhaust.. basically maybe lead oxide smearing as you try to polish it off the surface.

[@clannishkobra8965]

Do you repair cracked, corroded bead sealing parts of the wheel? Just curious I work for a tire company and alway wondered how its done.

[@jdmustang4622]

Water helps with activity the acid

[@summershine_7702]

Thank you JD

[@TheMrhick92]

What if you used oven cleaner and baked it?

[@summershine_7702]

Interesting. I'm not sure. May have cleaned it but wouldn't have changed the fact that the big pipes had to be sanded. But damn oven cleaner might have really loosened the grime.

[@TheMrhick92]

@@summershine_7702 yeah I figure with it being exhaust that the grime on it is pretty much baked on

[@sakuraturbo3364]

I would go 80 grid work my way up

[@summershine_7702]

That's what I ended up doing and it was horrible. Went through 100 sheets of sand paper.

[@sakuraturbo3364]

I don’t even waste my materials on that not worth it

[@summershine_7702]

For sure. The customer was happy.
