I am in the process of purchasing a pressure washer and a foam canon as I refuse to take my new Acura RDX to a car wash! I am looking at the Sun Joe SPX 3000 is this sufficient for car washing, I am 62 and a woman and yes I love to detail my own cars however I have never used a pressure washer previously, I also just ordered a Deionized water system for a spot free dry. Do you recommend the regular car shampoo or the Ultra Foam? I am sunny Santa Barbara and wash my car weekly. Thank you in advance for any responses!!
