it's getting much colder outside + wind + rain =

i can almost sense winter creeping in. need to wash my G again this weekend.
im wondering how well my G35C dust cover will fit my Z.

im going to be opening the garage door every work day this winter so i know blowing snow will get on my Z.

shall i just buy a new cover for my Z?

i hate car covers in general...
also im not sure if dust cover + some blowing snow powder on top is a good idea... could = mold. or stains...
