Hey all, I recently bought a Seadoo Wake 230 Pro with a black hull

After two days of boating at lake eildon I took it home, gave it a wash and noticed a dirty great scratch through to the fiberglass on the bottom. Its about 15cm long and about 10mm wide but doesn't go much past the gel coat.

As you can't see it unless you get right under the ski and its not structural I want to have a go at fixing it myself. Both Spectrum and Gelcote make SeaDoo Black gel coat but I can't find either of them locally.

Has anyone found a stockist in melbourne? or can you recommend a different brand that will match with SeaDoo factory black?

Also it's my first time playing with fiberglass so any tip would be well appreciated.

I'll post a picture of the offending mark when I get home.
