This is the only wax I use on my boat for as long as I can remember. It's so easy to put on and take off that I've done the exterior of my 32' Wellcraft by hand with Royale. One of my secrets is that I'll put a thick coat of wax on the boat before I put it away for the winter then simply wipe it off with a terrycloth towel in the spring. This wax can be left on indefinitely without causing damage to the hull.
