Doing a hull restoration is a 9 day job for a retired civil servant:
1. The Blue gelcoat is not the same thickness everywhere...watch when you sand. Seems the middle of the hull has the thinness gelcoat;
2. To get rid of big scratches I pressure washed the scratch, To apply the blue paint from the factory I first mixed the blue resin with hardener like you get with a fiberglass repair kit and it turned the perfect colour blue and applied layer after layer with the non red tip of a regular paper match, wet sanded with 600, 1200 and 2000 then buffed 3 layers of compound on to the scratch, applied no water wash wax product and it disappeared completely;
3. The black stripes are black gelcoat and can be sanded and buffed to perfect state;
4. The method that works is wet sand with the 3 papers, buff 3 layers of compound and apply no water wash wax product;
5. Sanding takes at least 15 minutes to 30 minutes of applying major pressure on the wet sandpaper or more per scratch...its a man's job;
The results look like this:

5 year old Blue Hull
p.s. I renamed my boat Le Zephyr and put her Canadian numbers on too
Le Zephyr means a western wind in old Greek and a soft gentle breeze in modern Greek
