I have just finished sanding the hull of my boat several times 800,2000,2500 wet. Now, I am (I think) ready for the vinyl lettering to go on. Question . Should I use the cleaner that comes with the poli-glo kit? Or should I skip the cleaner and just let the guy use his cleaner and apply the lettering, then poli-glo wax over the finished product and not bother using the cleaning agent at all? Or, use the cleaning agent and still have the letter guy use his cleaning also? Then wax. Thanks as always, Keep it up, Ctskip
