My roof molding needs cleaning and protecting. All of the cleaning and protectant stuff I have is very specific to it's application. Compatible with rubber, and not vinyl and plastic. Other is compatible with vinyl and plastic and shouldn't be used on rubber, etc...

I was under the impression that the roof molding was rubber, but feeling it, now, I'm really not sure.

And with this, detailers in the past have used protectants on it that have bled down during rain and left me cleaning my windows after every storm for a month or so due to an oily residue.

So, what material is the roof molding and/or what have you used on the roof molding to keep it clean and protected?

 

Pre-wow will work well to clean this up and the brush it has supplied will help you work it into the textured rubber/plastic. From what has been said on NAM, black wow will also protect it better than some of the other options out there.

Personally, I just use a diluted all purpose cleaner and an soft bristled toothbrush to clean this. Then to protect it I've been using prima infinity, which has been ok. The durability isn't bad. Much better than back to black, but not ultra long.

 

I agree with how NJ Mini does it. A diluted APC with either a horsehair or nylon detail brush. I would then protect it with Ultima Tire & Trim Guard Plus. UTTG+ has great durability and is very easy to work with!

The protectants that were used in the past were silicone based products and what you saw running down your glass was the silicone that just sat on the surface instead of being absorbed. A trim specific product, instead of a do-it-all dressing, will solve that problem.

 

I clean mine with Adam's APC and apply a light coat of Mothers Back to Black.
