I have been lurking around reading on what I need to buy. A friend of my owns his own detail business, so I get my towls and what not from him when he places an order.
I daily drive the car for the most part. (3-5 days a week) car sits in the sun at work, but is garage kept when at home.
Is clay bar needed? It's a brand new car, that seems a bit much but what do I know. This is why I'm reading and asking. I hand wash the car once a week, and pay to have it detailed once every 3-4 months.
Yes, new cars are filthy with rail dust, clay bars removes this.
