FAQ
What is the best car cover for outdoor winter storage?
A breathable, water-resistant full cover on a clean, dry car, with straps.
Waterproof or breathable?
Breathable lets moisture out; waterproof keeps rain out. Outdoors for long periods, breathable is kinder.
How do I stop a cover blowing off?
Use under-body straps and an elastic hem.
Should I cover a dirty car?
Wash it first; grit under a cover can scratch paint.
Which one to choose
For a general car, a full sedan or SUV cover with straps. Use the Civic, Pilot or Corolla/Civic covers only for those cars. Treat the inflatable tent as a separate option needing space and power.
