So, I bought some color changing TARDIS pint glasses from ThinkGeek, but the decals on them come off way too easy. So we got a replacement set (for free) and I coated them in this stuff:

So now the question is, are they safe to drink from? The entire outside is coated in the stuff. It says it's a permanent, waterproof coating, so I've no reason to believe it'd be a problem, but I can't find anything on the internet to confirm or deny this reasoning.
So help?
