Make sure you follow the directions exactly. When they tell you to thoroughly dry the tank, that's what they mean. When I thought mine was dry a stuck a hair dryer in it on high for another 20 minutes. If its not done right you'll have problems later with it not adhering properly. It's not difficult. You just want to take your time and make sure you follow the steps properly.
The lines should flow freely.
By the way, your usually better off putting all Ironhead questions in the Ironhead Section of the forum. Your likely to get some really strange answers if you don't.
