Flat bottom

OK, I need some help. I have a p15 that (hate to say) hasn't been used in awhile. It sat in my evergreen (storage container) all summer (hot) and not supported very well (my falt) sat on a box about 4' x 4' sad to say the bottom is kind of flat . I just built a rack in the garage (cooler temp). Was thinkng of filling with hot water to get the shape back,Do you think it will work? Any other ideas?
Thanks Jack

I don't know enough about kayaks to open my mouth but there are plenty of folks, I'm sure, that will be willing to give you some advice.

For what it's worth, there are several of good threads on this site that discuss proper ways to store kayaks.  I personally have mine hanging on the wall supported by slings.

Storing any yak on its bottom is a bad idea...I have seen many get tatered over time, especially if its on something with a small surface area such as your box or a cart is even worse...especially when its hot. Here's how I store mine...

Your proposed "hot water" idea is competent and workable.

Keep "total weight" in mind.   
Water weighs 8-pounds/gallon.
Provide multiple "(wood) block supports" to limit the range of motion.

Your goal is to obtain motion (yield) but you don't want that motion, under the influence of hot water & weight, to go out of control.

Yea, I just didn't pay enough attention as I have been busy. Was supposed to be a temp. spot but ended staying all summer. It is not to bad just not like it should be. Thanks everyone I will let you know how it turns out.

At the body shop they put heat lamps on bumpers and the large dents pop wright out.

Follow up: did this ever do the trick? I have a couple of dents I wanted to work out but thought your's already made a good guinea pig!
