also mate, is your CAI sitting on the radiator?? Careful that its not, over awhile the heat will eventually burn through the aluminum, i noticed before it was too late. Ive got the same system as you.
i painted the badges by:
sanding the plastic a little bit, using 600 grit wet/dry sandpaper
sprayed on some primer for plastics
then did 5 coats of paint (touch up car paint in a can from repco to match my car colour)
then did 5 coats of clear
i did the exact same thing for my car interior dash stripes..
thanks for the tip, ill check to see that my cai isnt leaning on my radiator!
