Our Super Cleaner is not really meant to be used as a car wash product because it's not meant to be used on windows/glass and if using it on your vehicle, it would also clean off the Hybrid Wax if used. So I wouldn't really recommend it for this type of application. It's better suited if you are trying to clean specific pieces on your car like your plastic trims, bug guts on the front of your vehicle, etc.
So yes, I would simply use another application of Hybrid Wax, however, before doing that, I would simply just use a hose to blast off the pollen and rinse/dry your vehicle with water. The previous Hybrid Wax application should make it super easy to rinse off the pollen with simple water. After the vehicle is dried, it should look great, but of course you can add another application if you feel like doing so.
