Does a regular black color A4, not metallic black, need a paint protection?

and if yes, should I get it from dealer?

 

ANY paint needs protection. Color does not make a difference. If you'd like some good background reading on car detailing and paint protection, follow the link in my signature to my registry page. There, follow the "How to make your car shine" link. I point to several web sites that do a great job of explaining what's involved in detailing and keeping your car in good shape.

 

PM me and I will send you a link to the best detailing how to I have ever read .
