Hood Repair/Adjustment

In a different thread over in rec.scuba, I talked about my issues with mask flooding,
and suggested it occurs more often when I'm hooded. One possible solution would
then be to trim the hood's face hole a little to give myself a bit more room.

If I were to do so (ie. use an X-acto knife or something like it), would it then be
necessary to "cauterize" the cut edges (eg. use a soldering tip or something) in
order to seal the face hole again or should I not bother?

Thanks.
