However as I recall you are right, Stainless indeed throws sparks but they are wimpy and few.
So once again I removed my trusty right side fang, reved up my angle grinder and sacrificed a bit of clip part that holds it on.
VIOLA!
Sparks.
Nothing to set fire to anything with but nevertheless there were sparks. I just had to use the right tool for the right job.

Trust me they are stainless steel. Test them with that gun, you will see I'm not full of crap.
I was acid etching aluminum most all day today, and after a while you get a sense for metals. Like... Ask your recycling freind. Ill bet he hardly ever really uses that gun. You can tell by the feel, the heft. "The texture. The taste! I love GOoooooLD"

As far as pollishing then is concerned just go with post #02-18-2005 03:54 PM and you cant go far wrong. One thing to remember: If you use a buffing wheel they get hot FAST so dont stay in one place too long and protect your fingers from getting burned.
Don't worry you wont ruin them Theyre Kryptonite!

Aluminum leaves black stuff on your hands, It drys out your skin until it cracks. I love to work with it but is messy.
