One more thought on Never Wet Spray versus Ultra-Ever Dry. Yes it's true that Never Wet was planned for aerosol spray and Ultra-Ever Dry is a non-aerosol, 2-step process. However, for my cash and peace of mind I prefer the 2-step process and not buying a primarily gas-filled, non-environmentally conscious product. You will find a great video from the manufacturer; on the Ultra-Ever Dry Review site; which shows you the Step-by-step Application and easy clean-up of Ultra-Ever Dry. More Product value and peace of mind. Don't forget your PPE!
