I just acquired, what I hope to be, a fun little sailboat that my grandchildren can learn to sail on. It is an '86 model and seems to be in decent shape. I know very little about boats but have picked some really valuable information today from this site in regards to "tweaks" and maintenance. The top deck has hair like crackl in the gelcoat in areas where I presume are stress points of the boat. They dont appear to be to be delaminating, but I am concerned, if in time, they are not sealed, they could be. Is there something special to put on these or is a good gelcoat cleaner and polish adequite ?? Thanks
