I just got some white face guages for my 89 Iroc and was wandering does anybody have some advice of what i can use to change the needles from white to red?Do I just use some red paint or a red maker

Just use a Sharpie Permanent Marker...I did mine blue, just used a blue sharpie, its lasted well over a year and looks the same as the day I did it!

Airbrush them.
