Gel-coat hair line crack repairs

[Iceman_cb]

hey guys
quick question here. i have some hairline cracks forming in my gel coat on my 2009 230 wake. the all seem to start from a screw or fastener attached to the hull. is there any type of easy repair for these that doesn't require me grinding out the crack. any help would be appreciated

nothing that I have ever seen, you need to grind the cracks out and the area around it and respray it with gel coat, depending on the size of the area I will grind the crack out and feather the edges out and just lay gel coat in the area with a putty knife or screwdriver to build it up and when it is hard I'll grind it down so it is almost level and then wet sand it with 1500 and then 2000 grit then finish it off with a buffer, as long as your using the same colour gel coat it blends in pretty good, but not as good as spraying the area.
