Painting a kayak

I have a few kayaks one of which is a white scupper pro.  I have heard from a few different people that the white plastic degrades faster than other colors.  Not sure if it's true or not but got me thinking what if I wanted to repaint my kayaks.  What time of paint would I use and what process would I have to us pe to complete the project.  Any help is appreciated.

From what I've read on the forums it seems that Krylon Fusion for plastics is what's recommended, but do expect to have to repaint or touch up after a while.
