Ran,

My one isn't, well it doesn't say it is, if you click on the link Paul supplied they do others which are, but I didn't think they were fully waterproof, which is what I really wanted. tbh my car get's pulled out every couple of weeks so it don't make much odds to me.

One thing I will say though not sure if that particular cover would go over a three door with the rear wing, I had a feeling it wasn't going to fit the rst at one point! just about pulls down to the wheels and tucks under the front and rear bumpers nicely.
