I have a car cover of unknow brand. It has very small holes in it, I presume to allow air flow. The problem is the cover allows a lot of dust to go through it. When I remove it it looks like the car needs a wash. Is there a cover that is impervious to dust in the air? BTW the car is always garaged.

All of these expensive cars being discussed on this board and nobody uses a car cover???

I have a California car cover works great. http://www.calcarcover.com/
They are expensive.

Mine came from Walmart & cost $20. Works great in the garage. Takes a minute or two with the California duster to make it look great before driving.

Easy to get on & off & stores in it's own bag.

I have a Covercraft Cover, I believe the part# is C80003, for my 68. It is a universal cover, but I swear it is made for my car. It fits very well and covers everything. No dust gets through and it is waterproof to a point. If there is a heavy downpour, it will go through, but it is designed to wick the water away from the car and also has anti-mildew agents in the fabric that keep it from getting moldy. It cost me about $137.00, and it is worth every penny so far.
