The word is chalkiness, it means the state of being chalky.
Their are ways to reapply the texture coating, their are products that you can get to simulate different sizes of tecture. You would have to do a test area to work out the size you would need, and then apply the Tan over the top in several light coats, so as not to fill in the area that shows the new texture. The best way for us here in Australia to get the colour right is to contact a paint rep and see if they can colour match to the inner side of your door panels, that should have the best finish and colour in that area, and make sure they are able to convert the paint in to a Plastic dye, and that they can get correct shean and a plastic promoter so the colour will adhere properly to the plastic.
I will keep you posted when i have something ready to release about the new coloured interior plastics also my friend.
