Well I removed the entire exhaust. I'll need a new gasket as the other one tore but I just got inpatient. The leak was the oil hose going to nipple behind the exhaust. Apparently the previous owner put a hose clamp on it and tightened it a bit too much and pinched the hose. So I cut the bad piece off and reinstalled it.
Now I'm onto repairing the hole in the gelcoat. I bought the 4 oz kit on ebay and after my first application, I had to add an additional coat.
And the previous owner decided to run a knife across the year stickers.. you know because they are so often stolen. argh.
After my gelcoat patch on yearly registration sticker
After first coat of gelcoat on the hole on the upper side of the hole.
after second application
After first sanding with 180 grit sand paper
This is my first attempt at gelcoat and after watching several youtube videos I'm thinking I can do this. After the 180 I'm thinking 400 grit, 800 grit and then 1200 grit. Then compound and wax, blah blah blah. All this to flip the ski. Well at least this is my practice one before I do the GSX I'm keeping.
Thank you everyone for your help.
