Clay bar would be best way to thoroughly remove the sealant.
Using regular dish soap mixed with water as your clay lube will also help to remove it. (also saves a lot of money instead of using regular clay lube)
Just wondering, did you apply our Hybrid Wax afterwards?
Before you clay bar, I would first try to fix the problem by spraying a very small amount of Hybrid Wax.
Sometimes streaks may occur with the Hybrid Wax if too much is applied so maybe try this out first.
