Graphene coat over 4 months old coating?

[KanYan]

Hi, I am new to this forum, hopefully this is the right place for questions. I will keep my question as short as possible.

 

I paid a shop to perform a color correction on a new car late last year, then I applied the Adam's Graphene coating myself. My car got into a car accident 2 weeks after the coating and need to replace the fender and bumper.

 

3 months after the car is fixed and painted, I purchased a new bottle of Adam's Graphene coating. I am planning to wash and clay the whole car, then do a quick polish to the new painted area only. Since I have the whole bottle, is it okay to apply another layer on top of the existing coating?

You can.  You may notice a slight difference in the depth between the old and new, but you should be fine.  And welcome to the forum.

Yes, but not necessary. When layering ceramic coatings, the law of diminishing returns applies. Applying 2+ layers does not result in 2x+ protection. Still, use a Fine Grade Clay bar if you still decide to layer.

The more I read your question, I don't think you should layer it. Applying the traditional/small bottle form so long after the first probably won't bond well, and may be a waste of effort, frankly. Use something else to maintain what you already have like Graphene Detail Spray and Graphene Shampoo.
