So what's your detailing experience? Have you ever got paid for your work? It started out as a hobby for me but a good friend of mine saw how good all of my cars looked and insisted that I do some work for me. The cars that he owns are pretty nice I would say. Veryon, countless Ferraris, Lambos including an LP640, Porsches, etc etc. I've nearly paid for the thousands of dollars of supplies with just his cars. I've detailed nearly all of them and used a leaf blower on all of them, too !! I don't know where you live but I don't live in an Iraqi sandstorm. So, I don't run into this problem. If the air that is being sucked into the leaf blower is so contaminated with sand, how do you avoid it when you wash the car? Surely the dirt lands on your paint, in your bucket(s), and glides against your paint as you wash. It's amusing that you're recommending a water filter but the one you recommend is a Mr Clean Auto-Dry and microfiber towels from Walmart !!

Here are cars that were detailed by me. It's a shame that they couldn't load high resolution photos onto their website though.
