Dr Shrink Wrap Experience?

Has anyone had experience shrink wrapping their own boat with Dr Shrink or any other product?

Any advice? Is it worth doing it on your own? Best places to buy the film?

You really have to watch putting it on not to burn anything. Also put plenty of vents if not everything will meldew or rust.

We shrink wrap with Dr. Shrink at work and it is expensive to do. They make seem easy, but it takes a lot of practice and a few hours, and you also need 2 people to do the job up until the point of actually shrinking the wrap.
