They typically don't get worse

As I explained, they occur in areas that flex. Once they form, they pretty much stay in those areas and don't spread. They don't generally widen, either. Unless you happen to damage the glass an area that has spider cracks and need to do a repair anyway, they really aren't worth fixing. If you're really determined to do it, either learn to repair it yourself or you can plan on spending hundreds of dollars per year on repeated gelcoat repairs that just crack again anyway.
