Query: Left Streaks Tha Won't Come Out

I tried this product (Meguiar's paint sealant) and it left streaks in my paint that I can't get out. I have used other brands of polymer paint sealant and they have been FAR superior to wax, and have never had an issue. I don't know what went wrong - I have contacted the manufacturer but haven't heard back yet. More to come...
