Hi guys. I used 6oz fiberglass e-glass, bought locally from composite material supplier, to laminate my surfboard. After hotcoat, the weave are visible through the hotcoat. I have not sanded. Is this normal? Previously, i used 4oz bought from greenlights and after hotcoat i did not notice the fiberglass weave visible through the coat. I wanted to take a picture but my phone battery ran out.
