Wondermike said:I'm not knocking anyone here for cleaning their car, but in some respects the paintwork on a 3 year old car that has been washed 6 times might actually be the same or better than a car that has been regularly washed with a poor technique.
Like Breaker said, put two cars together, one washed every week and one washed every 6 months, give them both a good clean, and they'll probably look the same.
Afraid thats not quite how it works, a vehicle correctly washed on a weekly basis and waxed will look far better than one washed twice a year. The paint finish dulls with surface contaminants, pollution etc. Thats unless you wash it weekly with brillo pad
