Ok. so you prefer to sell a product that last ''3 years'' at 100$ or a jar of fuzion at 175$ that last 4 month? You are making more money with a jar of fuzion .
Say the product does cost $100 but you don't use the entire syringe on the car. Just like you are paying $175 for a jar of Fuzion, that doesn't mean you use the entire jar. It's a simple concept really, whatever you charge for wax that lasts 3-4 months, you increase that price for a sealant that lasts 6-9 months, and for a coating that can last 1-3 years you mark it up even more.
