California Car Covers for mine. I believe I get the Superweave... pricey covers but 4 yr warranty that I just put to use. They just had me send a coded patch from the cover in with $10 and they sent a brand new one. They feel like the outer layer of a high tech rain jacket or something and fit the cars really well. Call and tell give them more info about what you're using it for.
good luck!

Will the breathable outdoor covers always let some amount of dust to settle on the car?

What is best for the outside use a breathable or non-breathable cover? Will a non-breathable cover do any damage to the car?

Thanks

a Non Breathable will trap moisture under the cover

Costco sometimes carries an extremely nice car cover for $40. Water proof, multi layer and breathes. I check all the time to get more for all my cars. They have them every now and then in different sizes.
