is this the stuff manufacturers use to underseal their cars?

where my car has been jacked up over the years. the underseal has been scraped off and i want to grind it back and replace it. theres no rust there.

can you get paint on underseal that gives the spongy effect same as under the fords as they left the factory?

only need to do little patches and spraying can be messy

cheers
