I assumed it was oe as that is what you specialize in. So if they didn't come undercoated they were just primer? I have seen other cars where they paint the underside in body color and I always assumed that was what was under the undercoat. Thanks I have learned alot form your posts so far.
ALL cars left the factory with undercoating in the front and rear wheel wells. If your car was coded for "undercoating" then the entire floor pan was covered....
I'm debating whether or not to undercoat the wheel wells....I find that most buyers go goo-goo for the ultra clean look.
I don't always go the OE route, the last Cuda I finished in Sept.2012 was painting completely underneath (long story).
