All ClearWater Design kayaks are made from LD Linear
polyethylene.  There are UV stabilizers in both the plastic and color.  
They do not require any treatment, but you may use a plastic cleaner
or protector.

Kayaks should be removed from their shipping bags immediately
because they can overheat and warp if left in the direct sun.

When strapping a plastic kayak to the roof of a vehicle, take care not
to overtighten your straps.  This may cause warping or denting where
the kayak is crushed against the carry racks.

If you develop a dent in your kayak due to improper storage or from
over-tightening your tie down straps, here are some suggestions:  
First, let the boat sit in the hot sun. Often the dent will come out all by
itself. If that doesn't work, prop the boat up on a couple of camp
chairs so that it is supported near the ends. Place a weight, such as
a bag of sand, on the indented area and let it sit for a couple of
hours. For best results, this should be done outside on a hot sunny
day. You can also warm the dented area by pouring hot water over
the area before placing the weight.

For short-term storage, kayaks should be turned upside down.

Kayaks can be stored on racks.  Ideally they should be hung from
straps positioned at or close to the bulkheads.  The kayak should be
on its side or upside down.  Do not hang from the carry handles.

All of our kayaks can be stored outside; they will not be harmed by
the cold.  

For long-term storage, boats should be placed out of direct sunlight.  
If you place a tarp or plastic over your kayak, remember that in direct
sunlight your kayak can overheat due to a greenhouse effect (as with
the shipping bag).

Cockpit covers are recommended to keep out rodents and other
undesirable creepy crawlers.

Footstops should be cleaned with soap and water if they start to
stick.  Even a small amount of dirt can interfere with their
performance.
