Doing it yourself saves your soul.
If you are trying to justify the expense of the products and time required I do not believe there is a price.
I think you would be hard pressed to find a detailer who would use
KLASSE. They tend to buy products in large bulk form that are easy on easy off so they can do a lot of cars a day.
Some detailers may use some good products but they are more likely to be mobile ones and not the guy onthe corner with the dogs chained to the fence with 20 cars out front washing them from the same single bucket.
