why do people sand blast?
because its easier?
because it gets the metal clean?
sandblasting is good for somethings,
and others shouldnt be touched with it. IMO
now ive never read up on this, because its worked well for me.
i used a plastic 33 gallon garbage can, filled it with a box of arm n hammer washing soda, and water.
i ran 4 electrodes on the perimeter of the can.
all hooked together with jumper cables to the + side of my 12 V battery charger.
and the negative to a rod in the center suspended the
parts i wanted clean into the middle of the can, being sure not to complete the circut.
was so much easier than sand blasting, and alot less mess.
supposed to be environmentally safe, and the results rocked!
if you had a pool, you could do a car body in your back yard!
check out my dash that i left in overnight. and spent 15 min with a wire brush.
