Polliwog 2012: Hull Paint, 3rd Coat Posted on November 17, 2012November 19, 2012 by coffeeadmin Saturday, I spent 1 1/2 hours sanding the hull with 220 grit and applied the 3rd and final coat of paint. Once the paint set (about 3 hour after application) I pulled the masking tape and applied another coat of varnish to the transom. [Show picture list]
