I want to repaint my 120y grille as it showing it age.
Any ideas on the best type of paint to use on plastic.

Any acrylic paint will do. its all in the prep, priming, undercoat etc. K & H sell all that you need, even a primer and filler in one which is useful in removing stonechips etc. Im just finishing repairing a mates front bumper cause she decided to take on a hare doing over 140km/hr... its debatable about who won, lol!

Your going to need a plastic primer otherwise acrylic wont adhere to the plastic for any lasting amount of time it will just chip off even when you give the car a wash or screw the grille back on. Otherwise supercheap sell plastic paints in a pressure pack in basic colors they have a binder premixed which helps them adhere to plastics etc we have used the satin black one and the grey they hold up well.

i use the yellow one which is a plastic filler and primer. After that any paint will do really.

Thanks guys I knew I would get the answers here. Cheers Bazz
