Painting billit grill with 3M paint??

I have an white 06 TRD sport that came with a billit grill from the previous owner, and it is the kind with the painted black on the flat edges between. I want to paint all the pieces with the 3M rubber coating, but am curious if I need to sand the whole grill for the paint to stick proper...getting in between would be a pain. Any one have any suggestions for me? Any help is greatly appreciated.

Thanks.

 

I had an all metal billet grill that came in silver and I didnt sand it and just sprayed it with 3M rubberized undercoating at it came out great. Just spray it without sanding it. You should be fine.

 

Awesome, thanks buddy

 

My billet style grill had the same thing. I scuffed it lightly with a scotch bright pad and the paint stuck fine. I only scuffed the front and used some black paint that I had.

 

Alright, I got the 3M rubber undercoating stuff...that's the right ish, right? I had to look all around town for the 3m stuff. This stuff will stick to the billit, right? I read some threads on here, and some people said it didn't adhere correctly...kinda iffy on spraying mine now as I don't want it to look like shit.
