It has been a while since I have been to this site, but let me assure all of you that the Ralph Lauren Paint finishes are all of exceptional quality. They are the best products Sherwin Williams manufacture and we will stand behind any of our products. The key to all of the finishes is to read the apllication tips on the back of the can or you may call our toll free number at 1-800-379-POLO (7656) during business hours. I have personally applied all finishes many times and have had great success. Mind you, I work for the company, but I am by no means a professional painter. It is also advisable to purchase the specific applicators for the particular jobs as they are specially designed to work together. Another idea would be to practice on a small scrap of drywall (available at any Home Depot) and practice on that. While some of the techniques seem a little daunting at first, they are not above a do-it-yourselfers abilities. My own mother can vouch for that! Good luck and Good painting!
