Quick question for you guys. I am looking to remove some light surface rust under the body of my 02 black trans am and want to touch it up to look factory. I am noticing that there was a greyish primer applied and then misted with color that appears dark green. What is the paint code GM uses for their black cars on the underside? I also have a 2013 metallic black GMC Terrain with what looks like the same color underneath. Is it body color or a different paint code?

Should be body color. The underside of my 2000 SS is body color.

Look inside the driverside door for RPO Code 41U...that should be the paint code for the Black used in 02.

Black WS6's are an off green color under the car and up around the trans and tunnel.

That's just they way they are, GM didn't fully paint the black ones

The green is just the base coat that didn't achieve full coverage. It gives a bluefish green tint when it's transparent do to lack of coverage.

As said above, my Black 2002 Firehawk was Green underneath too. Weird!

Always strive better than "factory" They dont go for the best quality.. they go for cost effective... You can do better, so do it!
