Essentially we first washed Myrtle really, really, really well and used the Bar Keepers friend powdered cleanser to remove stains, and rinsed it really well. Then we used 6 coats of Zep High Traffic Floor Finish, which goes on much easier than car wax!. Going forward we anticipate just using one coat each year. A week later the results are still terrific! (Note it does not repair crazing, fill in cracks etc but it did bring out the colour of the fibreglass gelcoat and make it nice and shiny).
