Try making a scraper out of an old saw blade (hacksaw, sawsall, etc.). I snapped mine to length drilled a hole in the end and then ground it to the shape I wanted. I also ground the teeth off and rounded the edges, which has so far allowed me to fly with it. Much superior to the cheap scraper that they come with.
But better to find out now than when your teeth are banging together like castanets. <img src="/images/graemlins/crazy.gif" alt="" />
