Hi William, I would suggest that you do a few tests. I would suggest making a lay-up of two layers of BID large enough so you can cut four strips from it, each 1" x 6". The easiest way to do this is use Mark Langford's technique of putting the glass and epoxy between Visqueen layers and squeegee the resin into the cloth. After cured sand one side with 80 grit sandpaper. Make a sandwich out of two of the strips with the "Icing" between the strips. Only apply it along 4" or so of the strips so you will have a surface to grip to. After cure, try pulling the two strips apart. Make your own decision based on your adhesion tests. Try the same test with Poly Fiber's Smooth Prime between the two strips. I am betting the Smooth Prime test coupon will win hands down.
This should give you the answers you are looking for.
