I removed all the swirl marks with a fine cut compound. Polished with a Pro machine glaze. Then finished up with an ultimate polish.

If I wash the car, will the washing remove the oils in the polish? Just what would be best result. I want to apply a sealant. Then a couple layers of wax. Thank for the advice.

 

The polishing oil should be removed so that the durability and effectiveness of the sealant will not be affected. You can wash your car or use a product like Griots pre-wax cleaner.
