Tony,
Forget the microwave. It won't heat glass cloth. Microwaves heat the water
content
of items. No water content to fiberglass cloth. At least there better
not be any water in the cloth.

I'm preheating the job area, the Lift Pin external reinforcement lay ups,
and mixing the resin and hardener under workshop spotlights that generate a
lot of localised heat. The glass cloth though is cold, and I am wondering about
placing it in foil in the oven to heat it up pre layup. I even thought of
microwaving
it, when my wife isn't at home. Any thoughts on the wisdom or otherwise
of doing this? I want to make the cold cloth as conducive as possible to
allow ingress of the resin into the individual fibres of a single thread, as I
occasionally have had some small splinter strait ions in these layups that
appear
to be micro dry areas along certain fibres, but the matrix between them is
fully wetted out. Thanks in anticipation.
Regards
Tony Renshaw
