Can be done, but must be cautious. Use a small sandblaster, or a sandblaster set on low (expand on this: distance, angle, etc.). | Can be done, but must be cautious. Use a small sandblaster, or a sandblaster set on low (expand on this: distance, angle, etc.). | ||
*Can sandblasting "increase" rust? Or, if the rust is removed and the metal is sealed, shouldn't it be eliminated? Some thoughts on this are: | *Can sandblasting "increase" rust? Or, if the rust is removed and the metal is sealed, shouldn't it be eliminated? Some thoughts on this are: | ||

*Another argument against rust "treatments" is that many of them require the surface to be lightly rusted first. "Inducing" rust seems wrong to people. | *Another argument against rust "treatments" is that many of them require the surface to be lightly rusted first. "Inducing" rust seems wrong to people. | ||

*One recommendation is: after sandblasting, remove some more of the surface metal by sanding with sandpaper. This is done to remove the salt, sand, moisture, etc. from the surface. | *One recommendation is: after sandblasting, remove some more of the surface metal by sanding with sandpaper.
