For garage storage, you may want to look at what body shops cover cars with. The brand I bought from a body shop supply house is called Smart Plasting Sheeting. It comes on a very compact roll and is 20' wide by
320' long. It is marked as to which side goes against the cars paint. Once the car is clean, just cover the entire vehicle with this plastic sheeting and it sort of ***** itself to the car like cling wrap. You can also use painters tape to tape the edges to the garage floor in case you have a breezy location....this also helps keep dust from getting to your rims, chassis, etc. The beauty of this stuff is us it once, throw it away. No drama with trying to clean a car cover, scratching, etc.
I think I paid under $70.00 for the roll.
Cheers,
