This video shows you how to repair a dented kayak. We boil some water ahead of time, then we use air pressure inside the hull while applying the hot water to the dented area. Once its hot the material will get soft and the air pressure will get the dent to mostly pop back out. This was a fairly severe dent that we purposely put into the hull to show the repair technique... so we had to use a bit more force by hand than just the pressure to remove - but as you can see it is a fairly simple repair to make at home. If you have questions please ask.
