Painting a bong?

Hey guys,

I recently purchased a new bong and I've gotta be honest, it's as fucking stereotypical as bongs get. No lie, its literally this but with the colors reversed. But fuck it right? I fucking love how stupidly stereotypical it is, I love it for it's awesome colors, I think we're all entitled to at least one thing like that.

At any rate the unfortunate thing about this bong is that it seems to have been painted with some very cheap paint that is not water resistant. This means that each time I wash it the paint peels off in areas. At this point its getting kinda sad and the bong doesn't look as good as it used to. So fuck it, I figured why not repaint it my self as a fun activity and give the bong a fun memory tied to it.

So what I'm getting at here is, does anyone know of any good paints that can be used on glass and is waterproof which most importantly will not kill me through toxins or what not. I'll be honest, I'm not an artist so I haven't a clue about paint, I'm hoping some of the more artistic ents can help me out here!

Cheers :)
