So, what are other peoples choices for resin and why did they go that way? Also, how many layers of cloth were used, 12 or so?
BTW, I was looking at the US Composites lines of resins.

Either resin is ok for a sub box. Best to check the resin date since they have a shelf life. 3 layers of cloth is needed unless you are creating a composite core (i.e. basa core). Get a good roller to get the air bubbles out.
