craftgrrl | Silicone (sp...i know, I'm a terrible speller) Glue?

Hey gals,
I don't know if this has already been mentioned or not, but I checked the FAQ and couldn't find anything there....
But I can't seem to find that sillicone glue stuff that you need for the marble magnets. I went to A.C. Moore and Michael's and didn't find it ANYWHERE. Does Michael's usually carry it? I mean, maybe they were just out. But the thing is, is I asked a few of their employees and NONE of them knew what I was talking about! Weird...

Does anyone know the exact name of the stuff so maybe I can go in there and say it's brand "such and such"?

I've been using that 3M Scotch rubber cement-type adhesive, and it seemed to work well at first, but it's smelly, and it's so abrasive that i have to be really careful b/c it's been eroding the pictures right off of the paper! Nice, I know...

Do you think that if I can't find it at Michael's that Joann's might have it? hmmm....

EDIT: oh wait, I just found on the FAQ's that it's E6000? Can I buy it online? These employees have no idea what the heck I'm talking about lol
