Today was Blast Day.
We will call it a qualified success. It's no faster than regular sandblasting. You will still end up with sand in places you didn't know existed. It does a really good job removing paint and a fair job removing rust.
It goes through media at an alarming rate. I ran 600 pounds of media through it today and finished about 1/3rd of the bus. Since the media is now wet, you can't shovel it up and run it through the gun again. I'm going to try to dry it and reuse it. We will see how that goes.
The best part is not having to deal with the dust. No masks or hood necessary. It also doesn't warp the panels.
If I was to buy another one, I would find one with a ceramic nozzle. The metal nozzle in the Norther Tool kit doesn't hold up too well. I went through two of them today, and they are $30 each.
Tomorrow it will get a Ospho treatment to neutralize the flash rust and a coat of primer.
More to come.
