Window trimming techniques

While our prop is out for some work, we're putting new 1/4" LP Aero side
windows in the Aztec. A couple of the windows need to be trimmed to fit
properly. What methods have proved to be the most successful? Band saw?
cut off wheel? Any others? We need to take about 1/4" to 3/8" off around
two sides so a belt or upright sander won't work, but I intend on finishing
and beveling the edges once the excess is removed. I understand that we
don't want to use anything that will heat the plastic excessively.

Thanks,
Jim
