I use Poli-glow on CornDog and have been very happy with the results. The real key, though, is preparation, especially with a colored hull. CornDog is a 1976 M17, and her yellow hull was very faded. In order to get good results with the Poli-glow you have to get your gel coat down to a consistent even color. Rubbing compounds and polishes didn't do the job. I had to wet sand the entire hull, starting with 400 grit, then moving to 600 grit, and finally to 1200 grit, which gave it a nice consistent satin finish. Applying the Poli-coat is very easy. It's a clear liquid that you wipe on with a shammy type cloth, starting on one side of the boat, working your way around, and by the time you've finished the first coat it's time to start on the second. After six coats the hull is coated with a clear shiny reflective surface that make the hull look as bright as when it's wet. Durability has been very good, with only an annual one-coat touch up to keep her looking like new. Larry Yake
