I like to apply a quality paste wax to my hull prior to the start of the season. If the weather is still cold, the wax can set up and be difficult to remove by hand. I usually apply the wax in a 4' by 4' section, then buff it off with a cloth. To make the buffing easier, I apply some cornstarch to the cloth to act as a mild abrasive. I find it has reduced my work time by half.
