Pneumatic sander to polish underwater

[aaron7405]

Hi guys

I am planning to get a pneumatic sander to polish some tanks underwater. Does anyone has some experience with that_ any pneumatic sander model I sould look?

Thank you guys

Air tools will contain brass and/or bronze as well as oil... I wouldn't want any of that in the water.

You can buy oil less air tools, they use Teflon, etc internals but they tend to be very expensive. I'm not sure I'd want to use a pneumatic tool just underwater, they expel a lot of air at high pressure. It will make a heck of a mess.

Although probably not what you want to hear, you're likely best off using lots and lots of elbow grease for the sanding. you're arm will feel like it's going to fall off well before you'll be done, but will be the best for the tank. Good Luck
