A sedan needs very little preparation. Most problems come from small things left on: a window open a crack, an auto wiper that wakes up in the spray, or an old mast antenna.
It takes a minute. The restrictions are posted at the entrance.
Check every window, including the rear ones the kids may have opened, and close the sunroof fully rather than just to the tilt position. High-pressure water finds small gaps.
Rain-sensing wipers can start as soon as water hits the windshield. Switch the stalk to off before you drive in so the blades stay parked.
Most newer sedans use a short fin antenna, which is fine. If yours has a tall mast antenna, retract it or unscrew it before entering.
Make sure the trunk is fully closed. A trunk released from the key fob in your pocket may be sitting slightly open without you noticing.
A sedan used as a daily driver sees salt in winter and road grime all year, and that builds up underneath where you do not see it. Full Wash includes the underside, so it suits regular washes. In dry summer weather, Quick Wash is enough to keep the body clean.
Quick plus an under-car spray. The one for salted roads.
