Hey friend. You used the hairdryer on the tank. Full or empty or? I want to get mine off but nervous about an explosion if ya know what I mean. Thanks in advance.Here is a trick that my wife had me do ,and it works great. Avon makes a product called Skin so soft. Peel that label off as best as you can. Then apply some Skin so soft to you finger tip and rub the Gooey stuff away. It works great and does not harm any finish, including paint.
