filling screw holes?

thanks for the help so far, i already had a new tube of marine tex that i was going to use for misc dings in the hull, i guess i'll use it inside too. emailed minicraft about a match for my gelcoat color, never got back to me. will those generic kits be able to match somewhat seamlessly, or should i badger minicraft a bit more? i'm guessing compounding or wetsanding the epoxy into the rest of the hull won't provide a lookproof repair, so i'm kinda looking for a gelcoat (admittedly a bit faded) match at this point. preciate da help.
