E glass vs Volan? Which one is better for laying up fins? Is there a > difference? The difference is the finish on the glass. Standard E glass used in surfboard manufacture is finished with silane, which adheres better to s249a resin (according to my supplier) and is clearer. Volan finish does not function as well as silane when used with s249a resin and has a slightly green tint to it, hence the necessity to tape and trim the lap with volan glassed boards. However for fins you will probably not notice a difference in strength but with volan your patches will be more noticable on the board. Matthew Weaver
