| * Hand lamination without vacuum. The hand lamination will have more resin in the laminate and the surface seems closed. No idea if the voids are reduced or if there is just a closed surface. | * Hand lamination without vacuum. The hand lamination will have more resin in the laminate and the surface seems closed.

| * Vacuum infusion. Compared to vacuum bagging literature claims that voids are reduced with this technique. The VAP membrane technology might be a way. This promises a void free laminate with a high fiber content. | * Vacuum infusion. Compared to vacuum bagging literature claims that voids are reduced with this technique.

| + | * Degassing the resin. Is probably useless for hand lamination because bubbles are introduced during the lamination process. | ||
