I'd go for some biax with the mat already stitched to it. A little more
pricey but much stronger and should not be as resin thirsty. You'll get
more bang for the buck.

Can you use chopped strand mat with epoxy?
I read one article that says no and then I read another article that
says it is ok.
I read where mat must always be used between two pieces of woven
roving when using epoxy, and then I read another article that says it
is ok to bond two pieces of woven together if you use a thickened
epoxy between them.
I am confused.
I'm not building a boat. I am repairing one, so I will not be using
polyester, just epoxy.
Thanks,
Dan
