The underside of my Maro appears to have a rubberized under coating. Did some years come with Factory under coating or is this something that someone did later on?

Just curious, thanks!

 

I think it was a regional specific thing. My car was originally delivered to a dealer in New York. On my original window sticker it says:

New York Warranty Enhancements- $65
(see dealer for details)

I'm guessing that's the undercoating. Mine has it, and I've seen car's that were originally delivered to Texas that don't have it.

 

it's a regional thing , my car is a fla. keys car . white in color with this brown crud all around the eng. bay . when i'm bored with nothing else to do . i spray mineral spirits , small brush , paper towels , getting it gone in the places it looks ugly .

 

I'm not sure about the regional thing,got any pics of your engine bay with the ugly brown stuff?

 

I don't have anything in my engine bay just the underbody of the car. Thanks for the info.

 

whats wierd is I dont have any underneath but I do have some in engine bay, and it appears to be some in the fenders too not sure if previous owner did it though my car was a cali car originally so I dont think there would be a need for it

 

My car has undercoating, I think it was bought in minestoa or something??

Anyway, it did a good kob because it doesent have any rust underneath. Alot of it is gone now, though, from my leaky pinion seal.

 

I think it was one of those add on's that dealers try to get you to buy to line their pockets with your dough.

 

Maybe down south... I know up here it comes in handy if you dont want the car to rust.

I must say, that whoever sprays the cars though, does a really fast job. I bet the just hose the whole underside. I have found it on all kinds of bolts and nuts, and even baked on to parts of the exhaust!

 

My car only has it in the rear wheel wells.

 

The last time I bought a new GM car in 1975, the dealer was asking buyers if they wanted the undercarriage undercoated on site for $50 additional charge. Some did and some did not.
