I'm a Optimum fan. I'm a detailer and à reseller in Europe. I love OC/OG. More and more customers are asking for this product, but there is also another question from me and my customers. Will there be (soon) a coating on the market from Optimum to coat/protect interior surfaces for permanent (or for 5 years) as well. Think about fabric, vinyl or leather interior surfaces (carpets and upholstery). The other thing I'm missing is a fabric cleaner for carpets,upholstery and fabric tops. Power clean is to strong and will fade the fabrics.
Your other products are fantastic. Keep up the good work!
