Just wanted to add my 5 cents about paint protection etc.
Waxguard/Natureguard isnt worth the paper the contract is written on. Fabric protection can be of benefit though. IMHO
I manage a car wash. The type with the high pressure gun and foam brush. If these systems are used properly, ie: Presoak the car FIRST, this is generally the strongest detergent, then high pressure soap over the car to remove heavy dirt and bugs BEFORE using the brush, the foam (the foam in most has very little detergent quality) from the brush constantly flushes it so no dirt is building up and scratching your paint, then high pressure rinsing makes certain the dirt is gone. The waxes my wash uses are equal to anything you can apply yourself or better, esp the Clear Coat which is a silicon paint protection enhanced wax and finally USE the spot free rinse, which is JUST highly filtered water, NO chemicals or anything, ours is between 0 and 1 part per million suspended solids, unlike tap water which can be as high as 200ppm, you will get NO water marks if you rinse properly, without having to chamois the car at all. Cars I wash myself I will guarantee NO SPOTS.
IF you give the car a really good soak in Presoak, then high pressure soap really well you can skip the foam brush so nothing touches your car. You dont have to pack anything up when done either, just drive away. I was sceptical about these washes before I started managing one, now I know theres no better way to wash your car. PLUS its environmentally friendly.
If you want to find a good carwash look for Dilling Harris Equipment or PRO WASH Australia equipment. The
www.prowash.com.au australia website lists some of the sites with their euipment, but not the one I manage. BTW I only manage a single wash not part of a chain like Carlovers and Im not paid to say this. The above is my opinion about washing cars.
