Use low viscosity resin or warm it up before lay-up to get completely clear coat. This fabric was used for the Epoxy Test panel. The strongest type of fiberglass with the best impact and abrasion resistance. Tight weave makes this glass nearly impossible to wet-out clear. Used only as tape on keel line and hidden reinforcement. .
Carbon fabric is very easy to work with and in many respects, it handles like plain fiberglass.
Graphite fabrics are best included in protected areas where strength and stiffness are very important. I use carbon extensively for building rudders , cockpit coamings , hardware and internal reinforcement. Superb for coaming, cockpit reinforcement, components and where stiffness and good looks are desirable. Handles just like 6 oz. fiberglass. They dissolve in polyester resins but not in epoxy.
