Hey I was wondering if anybody has done a "blacked out grill" and had to get rid of the chrome on it. I'm planning on doing this and I just want an idea of what I should do.

Sand and paint.
You could take it to a sand blasting shop or you could just grind the chrome off.
But it's not chrome. Sandblasting/grinding the plastic grille is way over the top.
Hence the advice already given to just sand and paint.
Make sure the sanded surface is tight (won't lift off) and any glaze is roughed up to give a tooth to the new paint, and then shoot.

Bump... What if one doesn't want to spend all that time to sand every nook and cranny on the grill? Would sand blasting be too aggressive on the plastic. What about bead blasting or soda blasting? These methods, though more expensive,
would probably be more effective.
Would a self etching primer be needed on bare plastic?
Would an adhesion promoter and then a plastic specific paint be fine followed by a coat of clear?

I highly recommend that you sand lightly with 400, clean with a grease and wax remover (e.g. SEM 38373 or SemSolv 3837), and then paint it with SEM 39143 in satin (also comes in flat but it's really flat).
I have blacked out some fake "chrome" using this technique and it has worked really well.
SEM does not recommend a primer under their trim paint (SEM 39143) but maybe you could use some kind of self-etching primer instead of sanding. Maybe you could phone their tech dept. and ask.

taking chrome off is a B*tch. It took me a while with a sandblaster. There are several layers, but i had to take all of them off in order for powder to stick at the time.
edit: if it is metal the has real chrome on it and not chrome paint then you should sandblast, for the other stuff just sand it, you can blast it but get the right type of media not sand
I will be calling a specialty plating company today to get a quote on "Black" chroming my grill and headlight surrounds. I'm not sure how the black chrome will look, but I want more of a glossy finish as opposed to a matte finish.
Maybe I am being lazy and just don't want to do all that hand sanding.
