Factory rustproofing underbody goo?


Guest

The car's underbody comes from factory covered with some rust proofing goo. I noticed that it rubed off in few spots likely due car being put on garage lifts.

 

I'd like to fill in missing spots - does anyone know what to use?

I don;t think that rubber stuff you buy from the parts store is the same stuff. The automakers usually use something more similar to a rhino liner like you'd find in a truck bed.

I'd be interested to find out what this stuff is also. The undercoating is flaking off the rear wheel wells of our Forester. By any chance you think SOA would cover this under warranty? We have the 7 yr, 70K on the vehicle...

The sticky goo on our cars is called Cosmoline. If it's just a few spots no larger than a half dollar, I wouldn't even worry about it.

Rubberized undercoating from Eastwood is what you want if you can get the factory stuff. I've used it on different cars I've owned and its excellent bar none. I have the spray gun and wand for applying it.

If you decide to use a different product than cosmoline....you'll have to completely remove any remaining cosmoline or it won't adhere properly to the car.

subau has underbody coating as a recall for the BE chassis. if you go to the dealer you can get a bottle of it.

 

Thanks for the tip! Getting one from KOP. The question will be how to apply it...

Spray gun is how the techs would do it.

 

More details please? Does it need to be heated or something prior to application?

Don't forget about corrosion-proofing the rest of your car also.

 

I spray Corrosion Block all over the engine bay - particularly the battery terminals. I got hooked on this stuff because my parents have sold it for years and it's always done an amazing job of keeping the Mercruiser engine our ski boat super-clean.
