I still have zero complaints about the cover bought in the first post. I'm actually going to hit them up for one for my Suburban since it spends a lot of time parked these days (gets used on the weekends mostly).
The cover's most important job is to keep the bird off the cars.
Oh! One of the plastic "fastex" clips broke. Not because of wind or weather but because I yanked on it thinking it was released. I replaced it with one from an old backpack.
I have 2 of these for my 2 Mustangs. I needed something that was waterproof since they currently sit outside. I'm hoping I'll be able to put a garage up on the pad that they're currently sitting on in the next year or 2.
I'll try to remember to take a pic or 2 when I get home from work. It's a cottony type underside. The stripes on the Cobra are weathered, dry, and cracked. Fibers from the cover have stuck to it, but otherwise I've not seen any adverse effects on the paint itself.
Here are those pics. I'd say they're good for a year, maybe 2, in the elements. The cover on the Cobra is already starting to become a little brittle. It could be because it's a little cold out too, hard telling.
