Wet sanding using a AIr Compressor?

[MegHighway1]

The compound F9 did not cut through the oxidation.
Now will try wet sanding with 800 g paper.
What do you think about using a sander, DA, 6'' with an air compressor?

You could do irreparable damage to the skin of your Airstream.
I hope others will chime in.
There is so much info available on cleaning and polishing, please do your research.

Not advised wet sanding should be done by hand always.800 paper is to coarse,Start with 1500

HALT way too course I started with 600 and finished with 2000 on these....left them as is, no polish.

Polishing is not for the impatient...

But, if you don't want to sand w/1500 or finer by hand, try using a rouge or tripoli bar with your compounder. It'll cut through the oxidation - but it can also go too far. So take it easy, if you burn through the Alclad, the only way to "fix that" is replace the panel.

The pits are deep. Tom from Perfect Polish came over to take a look because I have been ordering compounds with him, and yes the pits are deep. NuviteF9 is not doing it and either is 3M Super Duty.
So the choices came down to:
1 wet sanding - I tried wet sanding over a square foot with 1000 and it did smooth out the pits. The color of the pits - little dark grey spots- remain. And the place that I sanded is pale and dull.
How do I know if I took off all the Alclad?

In the mean time I have been talking with car body shops that often use air compressors...which lead to the idea of using 1500 g with an air compressor so that I can limit the work on my good shoulder!
I do not want to cut the oxidation too much and remove the ALclad,which I am not sure what that would look like.

2) Pink and white emory bars may be better. Some say Black then brown then F9... What do you think? some say use a sisal wheel, others say use a grinding type buffer- not sure what those are.


But First...How do I know when sanding if the Alclad is OK.

(geez I wish there was a camp to learn this)

Yellow Jesco wheel and green bar. Then doubled up sewn cotton wheels with a Nuvite…your choice…G-6 or G-7…even C. Then Cyclo with S. Like Sherry said….not for the impatient.
