CornStarch

I tried using the power of the search engine, but I find it not very good at searching . Anyways, I wonder if anyone has tried to bump up their O.G. by adding cornstarch. I've talked to a few people in my HBC and they think it my cause a stuck mash or clog when I go to do my sparge. I'm assuming in a small amount it would convert, but I'm not sure. One member states that it's been used by people making Budwiper for competitions, then again he said it's rumored. I was wondering if anyone has tried it?

I thought the whole thing was really weird but here is a thread from a few days ago.
