Pollen will scratch through any wax or sealant! It has to be rinsed/lifted or it damages.
Something I have learned from experience: Maguires Gold-Class leaves a pretty nice finish, but it doesn't last long through washed, sun, or even weather. The liquid even more so.
Also- what did you use before the gold class carnuba? If the product contained any oils, it will prevent waxes/sealants from adhering to the paint.
In the peak of pollen season, I use Optimum No Rinse. It has polymers to basically buffer the abrasive pollen. It also happens to do a good job on bird bombs and most bug goop. All without scratching or affecting wax or sealant.
