spray gloss

[andthewaves.livejournal.com]

Quick question.
I have a can of spray gloss. I used it to make my painted picture frames look more professional.

But the can doesn't really have much information on it.
Can I also put it on fabric, like to seal off hand-painted t-shirts? Has anyone tried this?
I also bought CD wallets that have a sort of plastic-y canvas-y material on the outside. I was going to paint on it with acrylic paint... and I was wondering about finishing it off with a light layer of the gloss...

Kinda weird questions, but maybe someone has tried it.

Thanks a bunch!
