Im planing on ordering the supplies to cap my biesemeyer and am wanting to know if this sounds rit before I buy it. I'm going threw west marine I was Gona go to us composites but it amazes me how you can sell product with no technical support even tho there cheaper. Any ways 105 epoxy resin ,206 slow hardner, 406 silica , 727 cabosil , and 4 inch 17 oz biaxial Matt and stager the seam so it'l b 6 inch wide finished. Would you change anything ? And is the mat to heavy? Im doing 3 layers of mat inside and out with 50 /50 silica and cabosil to fill holes and as a last coat over the mat.
