There is a dent or depression in my hull. What can I do about it?

The first step is to put your kayak in direct sun for 4+ hours (try to put on a soft grassy area). Normally, the plastic will return to shape on its own. If it does not, try using weights or other heavy objects while leaving it in the sun to push the dent out. Almost boiling water can be used in absence of sunlight.
