You are better off just leaving them and wet sand them smooth with 800/1000/1200 grit progressively, compound and wax.
Will make them a lot less noticeable.

Trying to actually repair the stress cracks is usually fruitless. Stress cracks appear because of flexing in the area, and will usually return. Most often seen in the radius areas in the splashwell and around where the consoles meet the hull/top cap.
Two areas with a lot of flexing in the hull.

To do a solid repair, the gelcoat has to be ground down to the resin/mat layer.
Then if there is no damage to the resin layer, new gelcoat has to be built up, color matched, sanded, etc. Expensive if done by a glass shop, with no guarantee they will not return the first time you whack a wave the wrong way.
