I'm going to spray my front grill (around headlamps etc) black, but I need some help!
I have a primer that is suitable for plastic, do I need to rub the grill down with sandpaper, or can I just decontaminate and spray on?
Any help much appreciated

Cheers

i'd sand down with fine paper and then decontaminate, good luck

or use a scotch pad to key the surface

i have just put mine on this minute. done the kidney and head light grills.
use some fine paper to rub down. dont use that plastic primer, you wanna use etch primer(acid8) from halfords. etch primer eats into the material so it dosent flake after a while. then sprayed them satin black and bake them in the body shop booth. not sayin you gotta do it this way just advice. but they have come out absolutly mint

done mine a few weeks back, just used scotchbrite to key it up then had a few coats of satin black! no need for lacquer or primer really!!

as above,done mine 3 weeks ago,roughed it up with some wet and dry sandpaper then a couple of coats off satin black with no primer or laquer,its not chipped so far good cheap mod that makes the front end look much more aggressive

Great advice, cheers guys.
I'll post up a pic when its done!

Same as lads no primer used on mine tryed satin and decided to go matt think it look ace so did my grill on my 525i track car aswell looks treats.
