buy the kind that was made to match your boat. gelcoat.ca They are the OEM supplier. It will match. Of course, you are matching to a 16 year old boat, so it your boat finish is faded or yellowed, it won't be exact. I used their repair kit on my speedster and had to do a gouge that was about 2 feet long and almost an inch wide. When it was finished, you couldn't tell it was ever there. Its a complete gel cote repair kit and comes with the 2 parts paste and hardener. Its easy and takes a few hours. If you have any questions just post em up.
