Re: 2002 Pontiac Montana Error code P0420

So can anybody tell me how to clear out my catalytic converter? Also, would I be able to squeak by the emissions test if I had the check engine light turned off right before I went to the test site? One last question, has anybody ever heard of or have experience using the CRC Guaranteed to Pass Emissions Test Formula? Here's a link from Amazon:
http://www.amazon.com/CRC-05063-Guar.../dp/B000CIPUR8

Apparently they sell this at Advance as well. Never heard of it until yesterday. Can anybody provide feedback? Will this be an effective bandaid for me to get thru the emissions test? I appreciate all help and advice
