Thanks Ed After reading that I think that I may have not added enough catalyst to the skin coat. Temps were hot that day and I decided to use a little less catalyst to increase my working time. I did not want the part to set up too fast. At least it was only in a few small areas. It's fixed now. I will do another light sand and then another coat of primer and it's going on then boat hopefully by this weekend.
Here is a close up of what alligatoring looks like.
