Re: Surface cracks
Virtually impossible to tell the true extent of the problem based on the limited details provided.
My first reaction was like Caleb's: Minor gelcoat crazing or stress cracks; simple fix.
But, on second thought (after seeing the OP's bottom paint comment) I'm not so confident...
Pictures or a more complete description would help immensely in getting a set of opinions that may be of more use.
