The trim on my 2020 Honda Ridgeline from the factory is a dark gray color. What will it do to the gray color, turn it black?

While this product does have color enhancing properties, it will not change the color. If in doubt, simply test a small, hidden area to see if the end result is acceptable. Hope this helps!

can this be used in combination with 303-aerospace (UV) protectant for plastic/powdercoated outdoor furniture, or is it duplicative?

Unfortunately, 303 Aerospace Protectant is not compatible with this product. Thanks for the question!

Can I apply a ceramic coating after applying this to any exterior trim?

I did it on my plastic trim and the metal that is textured metal on my tri-fold bed cover on my f150 and later on the same day it got dusty but after I hosed it the next day you can see it doing it’s thing and has lasted a few months since I applied it and my truck is always outside never in a garage. So I believe so.

Can this be used on car interior

The Trim Coating is best used on exterior plastic, vinyl, rubber, etc. For the interior dashboard, interior door coverings, etc. I recommend the 303 cleaner followed by application of the 303 Aerospace UV protectant. Have used My car is 12 yrs old and the interior still looks new.
