Once you've gotten the hang of how to restore headlights, it's time to get your name out there. 

If you're planning on doing headlight restoration as a side business or starting small, word of mouth is usually enough marketing for new customers. However, if this will be your primary source of income then you'll need to invest some time and money in marketing. 

An easy way to get your name out there without spending too much money is to walk around parking lots putting flyers in the windshields of cars that have foggy headlights. With a few hundred cars in the parking lot, just a 1-2% conversion rate could put hundreds of dollars in your pocket. 

You could also partner with local automotive dealerships, rental car dealers, and taxi services to have a steady stream of customers.  You'll need to perfect your elevator pitch, but the number of cars you'll have will be a great source of income. To improve your offer, learning how to detail cars can give you a huge advantage on your competition as well.
