I went to this dallas car wash last week and used the free rain x coupon and my car still looks clean even after I got caught in the hail the other day. I have never had the rainx on a car wash, I am not sure if this is unique to this white rock car wash in dallas so if you are looking for a car wash that is friendly, a fair price has a FULL service ( gasoline, wash and detail) then go here. They even have free coffee in the mornings :) \r
Nice family run business.
Pros: great job and free coffee
