Even if you don't have a ceramic coating on your car...
You still need to wash your car even when it's rainy. Why? Because you're exchanging the old dirt for new dirt on your paint, which has several benefits for you long-term.
First: By washing your car every couple weeks rain or shine, you're not allowing harmful contaminants to adhere to your paint and being they're slow but inevitable destruction of your beautiful paint.
Second: By washing your car every couple weeks rain or shine, you're staying on top of the light cleaning so that when you're due for your annual professional detail job, your detailer can spend more time with lighter cleaning and less aggressive polishing (paint correction), and you'll spend less money and have a more beautiful car, win win win!
Think of it like brushing your teeth... you brush your teeth every morning don't you? Even though you're just going to eat and get them dirty all day aren't you? You don't leave your teeth to degrade month-after-month until you're finally ready for your annual professional dental cleaning do you? Your car's paint is exactly the same! You don't get a cavity from eating one piece of candy, but eat candy for months upon months without brushing your teeth and what happens? Your car's paint is EXACTLY the same!
So... muster up the courage to wash your car regularly, even when it's raining. You'll love your car more, and you'll save money at your detailer's, and your resale value will be higher.
If you do have a ceramic coating on your car...
congratulations, you're smart and you have the best protection available.
But this doesn't give you permission to totally neglect your car during our 9 months of rainy stormy weather! Regular, simple washing is still the best defense against paint degradation, even if you have a ceramic coating. Besides, by now you know that washing a ceramic-coated car is ridiculously easy isn't it?
