Radio Shack sells ferric chloride in 16oz. bottles in-store for $4.50.. If you warm it up and agitate it while etching, it works pretty good.

My local Radio Shack still carries it and it's still listed on their website as "available in store"..

Almost any kind of paper will work to a degree but glossy ink-jet paper seems to work the best.. *I always used the JetPrint brand from Staples.

Dude!! I absolutly hate that stuff we got like 5 bottles of it on sale and when i tried it it started smoking in the *and it almost makes you pass from the fumes *lol.. i have to try that.. do you just put it in like a water bottle with foil inside the close the lid?

Man... its almost gone but i have another one that has a 16%Hydrogen Chloride (the same active ingrediant in the works) would that still work or is there something else that makes it do that.

...lazer... ;D ;D ;D

Im gona try it with a 2 liter bottle later.. that should be biggg.
