I'm looking over the car care guide and under Spot removal there is the line "Never use aggressive products to polish the coating or remove surface contamination."
What are examples of aggressive products? Since Opti-coat is chemical resistant I would think any chemical product is okay to use. That includes products like power clean and an iron removal on the car body.
I already have my car coated with Opti-Coat Pro+. Can I apply Power Clean directly on top of Ferrex without rinsing the Ferrex off?
Also why shouldn't I use Power Clean and Ferrex every two weeks as part of my wash?
