Does anyone know where in Western Australia i can get chrome dipping done? Just for the strips down the side of the car (BA XT) and for some Bumper inserts and the grill and surround.. And, is it expensive?

When you say strips-do you mean the rubber door bumps?
These won't chrome!
In last 3months this is what I got off eBay for my BA-XT-

*BA grille with chrome surround as on fairmont ghia=$75
* Chrome bumper inserts as on Ghias=$35 enough of to do front & rear.

Hope this helps!
