I just picked up my S2000 and want to have the underbody coated with anti rust paint similar to POR 15. Anything I shouldn’t have painted under there (control arms etc.)?

I live close to the ocean and rust is a big issue where I live. I just wanna keep it as clean as possible. Any advice would be appreciated!

 

Do not paint. Paint and undercoating trap water underneath and increase corrosion rate. Treat with fluid film or similiar.

 

Thanks for the advice. I will take this into consideration.

 

Unless the existing metal has rotted out, leave it alone paint/rubber coating wise. But I second a fluid film type option for rust protection. Instead of fluid film, I recommend woolwax as it has almost no smell to it. My daily driver is coated with fluid film and in hot days the smell is noticeable.

 

I would use a lanolin based product, that never really dries, doesn't trap the moisture and remains clear. I believe Fluidfilm is one of them, but double check
