This seems to me like "alligatoring". This can happen when your poly/vinylestet gelcoat is applied too thin. This results in too much styrene evaporating relatively. And because the styrene is a reactive component of the resin, the resin does not fully cure. This is how gelcoat stays reactive on the surface, but if the layer is too thin, the whole layer does not cure properly. The next layer of resin the attacks the semi cured resin, resulting in these wormy imperfections. To avoid this, use a fine brush, as brushmarks are the easiest attacking spots for alligatoring. And then apply the gelcoat a little thicker. And as even as possible. Best way would be a gelcoat spray gun.
