questions on bottoms (barrier coat/bottom coat)

I've sanded the old ablative bottom coat off my CD27. I'm down to the gelcoat, but it's not clean...where the bottom has small concavities, there are bits of bottom coat. I plan to use Interlux CSC for the new bottom coat, but have a few questions. I notice that there are some vertical cracks in the gelcoat near the stern. There is no evidence of blistering anywhere on the hull. I had not planned to put a barrier coat on and don't know anything of the history of the boat. The boat is in the water for about 6 months of the year, and stays out of the water for the winter. Should I barrier coat? If so, what do I use to clean the hull? Can I just barrier coat over the small cracks?

Thanks in advance

Bob
