Anyone using Gordons carbon uni as backing, on the outside of the limb back with nothing over the top of it, glass, etc? Just curious how durable it would be under an epoxy finish. I've used it several times as a core lam under a wood veneer and clear glass. Any info would be appreciated. I recently built a set of my newly designed TD hybrid LB limbs using the Gordon carbon on the outside back and was very happy with the performance and shooting characteristics but have it covered with copperhead limb skins. I've been looking online for a suppier of carbon laminates with a smooth woven matrix on one side.
