How to fix faded plastic trim on a car
Black plastic trim going grey or chalky is often quoted as a paint job when it is not. Unpainted plastic gets its colour from the plastic itself. Sunlight breaks down the very surface, leaving a pale powder. The plastic underneath is fine. There was never a coating to fail.
What kind of repair does it need?
Restoration, not repair. The faded surface is cleaned off, then the trim is dyed or treated with a trim restorer that soaks in. A dressing mostly washes off within a few weeks.
The faded surface is cleaned off and the trim is dyed or treated. Ask for a dye rather than a dressing, and ask how long it is guaranteed.
What to do next
Ask a detailer to do it. If anyone quoted you paint for faded black trim, get a second opinion. Paint on flexible plastic that was never made for it peels. Ask for a dye rather than a dressing, and ask how long it is guaranteed. Expect to redo it from time to time.
