Protective weather cover for FJs?

Sorry if this has already been asked, I searched the posts but could not find anything.

I'm looking for a custom protective cover for my FJ that will keep the weather off of it while being parked outside. I live on the coast so there is a high salt content in the air and we all know what that does to metal. It should be tough and breathable with vents and must be able to attach to vehicle as we also get very high winds.

If anyone has bought such a cover or knows of a good vendor I would love to get a link or a pic.
