Kayak Cover For Outside Storage - Danuu?

I need to store my OK Trident 13 in the backyard on a retaining wall.  I've bought the Suspenz EZ Rack mounts and am evaluating options for UV protection.  I've considered building a multi-kayak frame and covering with Suntuf roof material, but that's a lot of work and takes a lot more space.  So I'm considering the Danuu Kayak cover - size "Punk".  What do you think?  Has anyone used Danuu?  Is there a better brand?  Do these covers work?  What else should I be thinking about?

I use to cover my pa with my wife's car cover

  They're great.        I hear a lot of good things about them.

Thanks!  I'll order one and see how it goes. 

If you don't mind the work, a standard poly tarp slightly larger than your boat, a grommet kit, and bungee long enough to go through all the grommets can be had fairly easily as well.  Get it large enough you can cut in half and grommet the center section on both halves an dnow you have to covers for the price of one.

303 and a danuu cover. The covers are great, a lot heavier than a tarp and last a lot longer. 303 is a uv protectant available at any paddle shop or auto parts store, soak you kayak before putting it away or every few months.
