Difficult to assess. I would just go to a car paint shop or an airbrusher and ask what it costs.

Would wait for that. Such parts will certainly be easy to manufacture and there will most likely be many third party manufacturers who will offer them.

It will surely quickly become clear who is delivering decent quality. Above all, the prices are likely to be depressed by the supply and the selection will be much larger.

Is real.

Any paint shop can do that for you. Just ask in your place. They do that with us.
