I usually wash my 2006 Kia Optima my hand but it hasnt't been washed in 3 weeks and is really dirty. I thought about running it through a touchless carwash at the Texaco station before hand washing it. I would use a pressure washer but don't own one. I have Prime: Acrylic and AJT on the car now. I was wondering how strong the detergent is in these touchless carwash. Do you guys think it will effect the Prime: Acrylic and AJT ?
