5 hours? That all....
Pah.... I had an 8-hour marathon session the other month. Complete wash, wax, top coat, wheels, interior, windows (inside and out) engine bay, suspension, exhaust, inside of glovebox and cuby holes, spare-wheel well and surrounding area.
I've even been known to remove my bumpers to clean the "inside" face of them.....
Call me an OCD man, but I do lurve a my car being clean. Which reminds me, some bird pooped on my bonnet today...
