Thanks, I emailed Optimum before finding this forum, and here's the response from Ronald Doyle: "GPS does have carnauba wax and sealant oils (which are fillers), all part of the all in one process of cleaning, polishing, and sealing the paint."
Now I'm pretty new to all of this, so trying to understand fillers and what he mentions as oils. What I'm concerned about is certain glazes have oils that will evaporate even if sealed.
Are we talking about two different things? Help me to understand. Thanks.
