Do. It.
On the NA, I bought some clear plastic covering, similar to a phone screen protector. It was a 60" x 3" roll, IIRC. Found it on Amazon. It goes on the same way as a screen protector. It saves the powdercoating getting in an out of the car. Personally, I don't think the car is much more difficult to get out of and actually helps getting out because you have the doorbar to push off of.
