Two of my race cars have bear metal floors, 1 aluminum and 1 steel and I'm wondering about using the spray Flex Seal on them. Any one doing this?

That sprayable Flex Seal in a can, is better than any 3M, Wurth, or any other undercoating I have ever used.
The only thing better is the water based stuff used by Diamler Benz, and Porsche, and other High End Automakers. But takes a special gun, and might be hard to get.
That Flex Seal works good, and is readily available. Win, Win!

What are you doing with this, soundproofing?

Back in my Collision Repair days. We just use Rattle can Undercoating to replace OE.
Only recently have I used the Flex Seal Spray . But I could tell just by the way it behaved after I sprayed it and it dried, that it was good!
Of course I did some test panels with different thicknesses , and tried to peel it off . It was stuck like crazy , And very pliable...

I actually used it inside the cab of a Ford truck to stop a water leak that was coming from the outside. This was over a year ago , it rains a lot here in North Carolina and it hasn't leaked yet .

If the leak you sealed is a seam , by sealing the inside ,( unless the sealer filled the void all the way to the outside) you've created a space where corrosion will flourish , unseen ,& unabated. J M E ....

I have used the roll on/brush on bed liner from Pep Boys on some 4x4 buggies for work. I was surprised at how well it went on and evened out. Used tape around the edges which removed to a nice straight line. I don't think you could tell it from a commercial spray job. The running boards on my 40 were sprayed on by a bedliner and they look like new years later. I scrape the mud off my boots on them before getting in. (Talk about a driver)

Yes, good point. But that will happen far down the road. Customer was concerned with a constantly wet floorboard, and stinky truck!
Hopefully it'll last another good 10 years, lol!
