Not at all the same actually. Armour Etch is an etching cream used to etch glass surface (as an alternative to blasting or laser etching), whereas rub'n'buff is used for antiquing frames, glazing, etc. Folks around here use it to rub into an etched surface to give it some depth or add color to an etched area.

yes.  It etches the surfaces, and doesn't cut into the glass like blasting does, but it still gives a permanent etch.

So, i finally bought the armour etch, lol, i don't seem to rush into anything! haha...

actually, with the holidays being over, i have some time to invest in playing.

few questions in getting started, the kind of stuff i wish i knew before i go and screw something up.

1. is this harmful to smell? should it be done outside?
2. will it clean up in the event of a spill/splash without blowing a hole in my formica?
3. what tool is best to apply it with? a paintbrush?
4. can it be cleaned off in the sink, or will it chew through the stainless? haha
5. time left on...ball park? what is the rule of  ?
6. materials:  can i etch just about any thickness of glass? will wine glasses etch? i'm afraid of the "surface etch" being too deep and weakening the glass--is that a possibility with AE?
7. i will probably do practice runs all over my bakeware this weekend, lol. 

any technical hands on "been there, done that" advice much appreciated!!   Thanks so much!

ha, good idea. never thought about etching my eye.  I guess if i run out of pyrex, i can always try that.

Thanks for your tips, i appreciate it very  much!
