The cloth should be fully saturated and clear, but no “puddles.” You’ll start to hear a sort of zipper sound with the spreader or squeegee, and there will be little to no resin piling up at the edge as you pull.
Think of the fiberglass as a sponge. You over saturate the sponge, it drips out all over the place and makes a mess.....ie, puddling and pooling. If you over wring out the sponge it will pull in air when it reforms it's original shape...i.e, air bubbles in your lam.
So how do we tell you what it should look like? It should look perfect if you do it right. Who ever told you that you can pull tons of resin out of your lam coat? That would be a waste of material? Resin is just glue to hold the fiberglass to the surface of whatever you are glassing. Resin has hardly any structural value...it's just glue. Remember,...saturate the cloth, let it wet out, pull off any puddling, laminate it down. even squeegee pressure, don't over work it. Laminate it..walk away.
