Changing color on interior parts

Thanks for all of the good advice & guidance, I'm very happy with my results.

I purchased the SEM Landau black and the prep. I first cleaned the door panels with simple green and rinsed throughly. I let them dry in the house for a few days while I waited for good weather to spray on the new color.
I used the prep as directed and then sprayed a very ligh coat of color, then applied another caot and let it sit over night. The next day I applied two more light coats. The panels look really great!

I did try some Dupli-Color vinyl dye on some old parts and it is way too glossy. The SEM landau black looks pretty close to the original Mopar black.
