If I can avoid buying a new one and spray painting the old one black and using your trick, that would be great.

To get the grey out, I coated mine in silicon fluid, and it looks good for now.

I may yet take it out and paint it with Rustoleum 7777 satin black. I have done this on my Saab Aero and it has looked good for years.
